The present invention relates to certain disubstituted octahydropyrrolo[3,4-c]pyrrole compounds, pharmaceutical compositions containing them, methods of making them, and methods of using them for the modulation of the orexin receptor and for the treatment of disease states, disorders, and conditions mediated by orexin receptor activity.
Orexin (or hypocretin) signaling is mediated by two receptors and two peptide agonists. The two orexin peptides (orexin A and orexin B) herein after referred to as orexins, bind to two high affinity receptors, termed orexin-1 and orexin-2 receptors. The orexin-1 receptor is selective in favor of orexin A, while the orexin-2 receptor binds both orexins with similar affinities. The orexins are cleavage products of the same gene, prepro orexin. In the central nervous system neurons expressing prepro-orexin, the precursor from which orexin is produced, are found in the perifornical nucleus, the dorsal hypothalamus and the lateral hypothalamus (C. Peyron et al., J. Neurosci., 1998, 18(23), 9996-10015). Orexinergic cells in these nuclei project to many areas of the brain, extending rostrally to the olfactory bulbs and caudally to the spinal cord (van den Pol, A. N. et al., J. Neuroscience., 1999, 19(8), 3171-3182).
The broad CNS distribution of orexin projections and neurons expressing orexin receptors is suggestive of orexin involvement in a number of physiological functions including; feeding, drinking, arousal, stress, reward, metabolism and reproduction (T. Sakurai, Nature Reviews Neuroscience, 2007, 8(3), 171-181).
The targeted necrosis of cells expressing prepro-orexin suggests the most physiologically important roles of the orexins are likely to be effects on arousal, feeding and metabolism (J. Hara et al., Neuron, 2001, 30, 345-354). A prominent orexin neuronal projection via the vagus nerve probably mediates central orexin effects on cardiac parameters (W. K. Samson et al., Brain Res., 1999, 831, 248-253; T. Shirasaka et al., Am. J. Physiol., 1999, 277, R1780-R1785; C.-T. Chen et al., Am. J. Physiol., 2000, 278, R692-R697), gastric acid secretion and gastric motility (A. L. Kirchgessner and M.-T. Liu, Neuron, 1999, 24, 941-951; N. Takahashi et al., Biochem. Biophys. Res. Commun., 1999, 254, 623-627).
Several lines of evidence indicate that the orexin system is an important modulator of arousal. Rodents administered orexins intracerebroventricularly spend more time awake (Piper et al., J. Neurosci. 2000, 12, 726-730). Orexin-mediated effects on arousal have been linked to orexin neuronal projections to histaminergic neurons in the tuberomammillary nucleus (TMN) (Yamanaka et al., Biochem. Biophys. Res. Comm. 2002, 290, 1237-1245). TMN neurons express the orexin-2 receptor primarily, and the orexin-1 receptor to a lesser extent. Rodents whose prepro orexin gene has been knocked out, or whose orexigenic neurons have been lesioned, display altered sleep/wake cycles similar to narcolepsy (Chemelli et al., Cell 1999, 98, 437-451; Hara et al., 2001, supra). Dog models of narcolepsy have been shown to have mutant or non-functional orexin-2 receptors (Lin et al., Cell 1999, 98, 365-376). Human narcolepsy appears to be linked to deficient orexin signaling, likely related to immune ablation of orexinergic neurons in the lateral hypothalamus (Mignot et al., Am. J. Hum. Genet. 2001, 68: 686-699; Minot & Thorsby, New England J. Med. 2001, 344, 692), or, in rare cases, to mutations in the orexin-2 gene (Peyron et al., Nature Med. 2000, 6, 991-997). The disclosure that rats, dogs and humans treated with the dual orexin-1/2 receptor antagonist, ACT-078573 (Brisbare-Roch et al., Nature Medicine, 2007, 13, 150-155) exhibited decreased alertness together with characteristic clinical and EEG (electroencephalographic) signs of sleep provides evidence to support a role for the orexin system in the regulation of arousal, sleep and wake states. EEG data indicates that orexin-2 may be more important than orexin-1 in the modulation of sleep/wake (P. Malherbe et al., Molecular Pharmacology (2009) 76(3):618-31; C. Dugovic et al., J. Pharmacol. Exp. Ther., 2009, 330(1), 142-151). Disorders of the sleep-wake cycle are therefore likely targets for orexin-2 receptor antagonist therapy. Examples of such disorders include sleep-wake transition disorders, insomnia, restless legs syndrome, jet-lag, disturbed sleep, and sleep disorders secondary to neurological disorders (e.g., manias, depressions, manic depression, schizophrenia, and pain syndromes (e.g., fibromyalgia, neuropathic pain).
The orexin system also interacts with brain dopamine systems. Intracerebroventricular injections of orexins in mice increase locomotor activity, grooming and stereotypy; these behavioral effects are reversed by administration of D2 dopamine receptor antagonists (Nakamura et al., Brain Research, 873(1), 181-7). Therefore, orexin-2 modulators may be useful to treat various neurological disorders; e.g., agonists or up-regulators to treat catatonia, antagonists or down-regulators to treat Parkinson's disease, Tourette's syndrome, anxiety, delirium and dementias.
Recent evidence indicates a role for orexin in the pathogenesis of Alzheimer's disease (Kang et al, Science Express, 2009, 1-10). Brain interstitial fluid levels of amyloid-beta were demonstrated to fluctuate diurnally in both humans and rodents with sleep deprivation in rodents leading to significant increases in brain interstitial fluid levels of amyloid-beta. Infusion of a dual orexin antagonist in rodents suppressed interstitial levels of amyloid-beta and abolished the natural diurnal variation of amyloid-beta. The reduction of interstitial fluid amyloid-beta levels is correlated with reduced amyloid plaque formation, a hallmark of Alzheimer's disease, and consequently the regulation of sleep time could potentially inhibit amyloid-beta aggregation and slow the progression of Alzheimer's disease.
Orexin neurons project to many regions of the brain associated with reward function (T. Sakurai, supra) and research, focusing on animal models of drug intake, reward, and reinstatement, has expanded the link between the orexin system and addiction. A comprehensive set of data suggest that drugs of abuse activate the orexin system, which in turn enhances drug reward or drug seeking (G. Aston-Jones et al., Neuropharmacology, 2009, 56 (Suppl 1) 112-121. Thus interactions between nicotine (J. K. Kane et al., Endocrinology, 2000, 141(10), 3623-3629; J. K. Kane et al., Neurosci. Lett., 2001, 298(1), 1-4), morphine (D. Georgescu, et al., J. Neurosci., 2003, 23(8), 3106-3111) and amphetamine (C. J. Winrow et al., Neuropharmacology, 2010, 58(1), 185-94) and the orexin system have been demonstrated. Additional studies from a number of laboratories have demonstrated an important relationship between the Orexin system and ethanol consumption. As examples, ethanol consumption in an alcohol-preferring strain of rat was shown to up regulate Orexin mRNA in the lateral hypothalamus and that an Orexin-1 receptor antagonist reduced operant responding for ethanol (Lawrence, et. al., Br. J. Pharmacol., 2006, 148, 752-759). Treatment with an orexin-1 antagonist has also been shown to decrease operant responding for ethanol (Richards, et. al., Psychopharmacology, 2008, 199 (1), 109-117). Other studies have demonstrated increased Fos activation of orexin neurons following contextual reinstatement to ethanol seeking (Dayas, et. al., Biol. Psychiatry, 2008, 63 (2), 152-157 and Hamlin, et. al., Neuroscience, 2007, 146, 525-536). Studies have also shown increased ethanol consumption following Orexin infusion into the paraventricular nucleus of the hypothalamus or in the lateral hypothalamus (Schneider, et. al., Alcohol. Clin. Exp. Res., 2007, 31(11), 1858-1865). These studies provide evidence that modulation of the Orexin system effects alcohol preference and therefore Orexin receptor antagonists are likely to be useful for the treatment of alcoholism.
Orexins and their receptors have been found in both the myenteric and submucosal plexus of the enteric nervous system, where orexins have been shown to increase motility in vitro (Kirchgessner & Liu, Neuron 1999, 24, 941-951) and to stimulate gastric acid secretion in vitro (Takahashi et al., Biochem. Biophys. Res. Comm. 1999, 254, 623-627). Orexin mediated effects on the gut may be driven by a projection via the vagus nerve (van den Pol, 1999, supra), as vagotomy or atropine prevent the effect of an intracerebroventricular injection of orexin on gastric acid secretion (Takahashi et al., 1999, supra). Orexin receptor antagonists or other down-regulators of orexin receptor-mediated systems are therefore potential treatments for ulcers, irritable bowel syndrome, diarrhea and gastroesophageal reflux.
Body weight may also be affected by orexin-mediated regulation of appetite and metabolism (T. Sakurai et al., Cell, 1998, 92(4), 573-585; T. Sakurai, Reg. Pept., 1999, 85(1), 25-30). Some effects of orexin on metabolism and appetite may be mediated in the gut, where, as mentioned, orexins alter gastric motility and gastric acid secretion. Orexin receptor antagonists therefore are likely to be useful in treatment of overweight or obesity and conditions related to overweight or obesity, such as insulin resistance, type II diabetes, hyperlipidemia, gallstones, angina, hypertension, breathlessness, tachycardia, infertility, sleep apnea, back and joint pain, varicose veins and osteoarthritis. Conversely, orexin receptor agonists are likely to be useful in treatment of underweight and related conditions such as hypotension, bradycardia, amenorrhea and related infertility, and eating disorders such as anorexia and bulimia.
Intracerebroventricularly administered orexins have been shown to increase mean arterial pressure and heart rate in freely moving (awake) animals (Samson et al., Brain Res. 1999, 831, 248-253; Shirasaka et al., Am. J. Physiol. 1999, 277, R1780-R1785) and in urethane-anesthetized animals (Chen et al., Am. J. Physiol. 2000, 278, R692-R697), with similar results. Orexin receptor agonists may therefore be candidates for treatment of hypotension, bradycardia and heart failure related thereto, while orexin receptor antagonists may be useful for treatment of hypertension, tachycardia and other arrhythmias, angina pectoris and acute heart failure.
From the foregoing discussion, it can be seen that the identification of orexin receptor modulators, in one embodiment modulators of the orexin-2 receptor, will be of great advantage in the development of therapeutic agents for the treatment of a wide variety of disorders that are mediated through these receptor systems.

The invention may be more fully appreciated by reference to the following description, including the following glossary of terms and the concluding examples. For the sake of brevity, the disclosures of the publications, including patents, cited in this specification are herein incorporated by reference.
As used herein, the terms “including”, “containing” and “comprising” are used herein in their open, non-limiting sense.
The term “alkyl” refers to a straight- or branched-chain alkyl group having from 1 to 12 carbon atoms in the chain. Examples of alkyl groups include methyl (Me, which also may be structurally depicted by the symbol, “/”), ethyl (Et), n-propyl, isopropyl, butyl, isobutyl, sec-butyl, tert-butyl (tBu), pentyl, isopentyl, tert-pentyl, hexyl, isohexyl, and groups that in light of the ordinary skill in the art and the teachings provided herein would be considered equivalent to any one of the foregoing examples.

The term “substituted” means that the specified group or moiety bears one or more substituents. The term “unsubstituted” means that the specified group bears no substituents. The term “optionally substituted” means that the specified group is unsubstituted or substituted by one or more substituents. Where the term “substituted” is used to describe a structural system, the substitution is meant to occur at any valency-allowed position on the system. In cases where a specified moiety or group is not expressly noted as being optionally substituted or substituted with any specified substituent, it is understood that such a moiety or group is intended to be unsubstituted.
The terms “para”, “meta”, and “ortho” have the meanings as understood in the art. Thus, for example, a fully substituted phenyl group has substituents at both “ortho” (o) positions adjacent to the point of attachment of the phenyl ring, both “meta” (m) positions, and the one “para” (p) position across from the point of attachment as illustrated below.
To provide a more concise description, some of the quantitative expressions given herein are not qualified with the term “about”. It is understood that, whether the term “about” is used explicitly or not, every quantity given herein is meant to refer to the actual given value, and it is also meant to refer to the approximation to such given value that would reasonably be inferred based on the ordinary skill in the art, including equivalents and approximations due to the experimental and/or measurement conditions for such given value. Whenever a yield is given as a percentage, such yield refers to a mass of the entity for which the yield is given with respect to the maximum amount of the same entity that could be obtained under the particular stoichiometric conditions. Concentrations that are given as percentages refer to mass ratios, unless indicated differently.
The terms “buffered” solution or “buffer” solution are used herein interchangeably according to their standard meaning. Buffered solutions are used to control the pH of a medium, and their choice, use, and function is known to those of ordinary skill in the art. See, for example, G. D. Considine, ed., Van Nostrand's Encyclopedia of Chemistry, p. 261, 5th ed. (2005), describing, inter alia, buffer solutions and how the concentrations of the buffer constituents relate to the pH of the buffer. See also Handbook of Chemistry and Physics, 84th ed., pp. 8-37 to 8-44. For example, a buffered solution is obtained by adding MgSO4 and NaHCO3 to a solution in a 10:1 w/w ratio to maintain the pH of the solution at about 7.5.
Any formula given herein is intended to represent compounds having structures depicted by the structural formula as well as certain variations or forms. In particular, compounds of any formula given herein may have asymmetric centers and therefore exist in different enantiomeric forms. All optical isomers and stereoisomers of the compounds of the general formula, and mixtures thereof, are considered within the scope of the formula. Thus, any formula given herein is intended to represent a racemate, one or more enantiomeric forms, one or more diastereomeric forms, one or more atropisomeric forms, and mixtures thereof. Furthermore, certain structures may exist as geometric isomers (i.e., cis and trans isomers), as tautomers, or as atropisomers.
The symbols and
are used as meaning the same spatial arrangement in chemical structures shown herein. Analogously, the symbols
and
are used as meaning the same spatial arrangement in chemical structures shown herein.
Additionally, any formula given herein is intended to refer also to hydrates, solvates, and polymorphs of such compounds, and mixtures thereof, even if such forms are not listed explicitly. Certain compounds of Formula (I) or Formula (II) or pharmaceutically acceptable salts of compounds of Formula (I) or Formula (II) may be obtained as solvates. Solvates include those formed from the interaction or complexation of compounds of the invention with one or more solvents, either in solution or as a solid or crystalline form. In some embodiments, the solvent is water and then the solvates are hydrates. In addition, certain crystalline forms of compounds of Formula (I) or Formula (II) or pharmaceutically acceptable salts of compounds of Formula (I) or Formula (II) may be obtained as co-crystals. In certain embodiments of the invention, compounds of Formula (I) or Formula (II) were obtained in a crystalline form. In other embodiments, crystalline forms of compounds of Formula (I) or Formula (II) were cubic in nature. In other embodiments, pharmaceutically acceptable salts of compounds of Formula (I) or Formula (II) were obtained in a crystalline form. In still other embodiments, compounds of Formula (I) or Formula (II) were obtained in one of several polymorphic forms, as a mixture of crystalline forms, as a polymorphic form, or as an amorphous form. In other embodiments, compounds of Formula (I) or Formula (II) convert in solution between one or more crystalline forms and/or polymorphic forms.
Reference to a chemical entity herein stands for a reference to any one of: (a) the actually recited form of such chemical entity, and (b) any of the forms of such chemical entity in the medium in which the compound is being considered when named. For example, reference herein to a compound such as R—COOH, encompasses reference to any one of, for example, R—COOH(s), R—COOH(sol), and R—COO−(sol). In this example, R—COOH(s) refers to the solid compound, as it could be for example in a tablet or some other solid pharmaceutical composition or preparation; R—COOH(sol) refers to the undissociated form of the compound in a solvent; and R—COO−(sol) refers to the dissociated form of the compound in a solvent, such as the dissociated form of the compound in an aqueous environment, whether such dissociated form derives from R—COOH, from a salt thereof, or from any other entity that yields R—COO— upon dissociation in the medium being considered. In another example, an expression such as “exposing an entity to compound of formula R—COOH” refers to the exposure of such entity to the form, or forms, of the compound R—COOH that exists, or exist, in the medium in which such exposure takes place. In still another example, an expression such as “reacting an entity with a compound of formula R—COOH” refers to the reacting of (a) such entity in the chemically relevant form, or forms, of such entity that exists, or exist, in the medium in which such reacting takes place, with (b) the chemically relevant form, or forms, of the compound R—COOH that exists, or exist, in the medium in which such reacting takes place. In this regard, if such entity is for example in an aqueous environment, it is understood that the compound R—COOH is in such same medium, and therefore the entity is being exposed to species such as R—COOH(aq) and/or R—COO−(aq), where the subscript “(aq)” stands for “aqueous” according to its conventional meaning in chemistry and biochemistry. A carboxylic acid functional group has been chosen in these nomenclature examples; this choice is not intended, however, as a limitation but it is merely an illustration. It is understood that analogous examples can be provided in terms of other functional groups, including but not limited to hydroxyl, basic nitrogen members, such as those in amines, and any other group that interacts or transforms according to known manners in the medium that contains the compound. Such interactions and transformations include, but are not limited to, dissociation, association, tautomerism, solvolysis, including hydrolysis, solvation, including hydration, protonation, and deprotonation. No further examples in this regard are provided herein because these interactions and transformations in a given medium are known by any one of ordinary skill in the art.
In another example, a zwitterionic compound is encompassed herein by referring to a compound that is known to form a zwitterion, even if it is not explicitly named in its zwitterionic form. Terms such as zwitterion, zwitterions, and their synonyms zwitterionic compound(s) are standard IUPAC-endorsed names that are well known and part of standard sets of defined scientific names. In this regard, the name zwitterion is assigned the name identification CHEBI:27369 by the Chemical Entities of Biological Interest (ChEBI) dictionary of molecular entities. As generally well known, a zwitterion or zwitterionic compound is a neutral compound that has formal unit charges of opposite sign. Sometimes these compounds are referred to by the term “inner salts”. Other sources refer to these compounds as “dipolar ions”, although the latter term is regarded by still other sources as a misnomer. As a specific example, aminoethanoic acid (the amino acid glycine) has the formula H2NCH2COOH, and it exists in some media (in this case in neutral media) in the form of the zwitterion +H3NCH2COO−. Zwitterions, zwitterionic compounds, inner salts and dipolar ions in the known and well established meanings of these terms are within the scope of this invention, as would in any case be so appreciated by those of ordinary skill in the art. Because there is no need to name each and every embodiment that would be recognized by those of ordinary skill in the art, no structures of the zwitterionic compounds that are associated with the compounds of this invention are given explicitly herein. They are, however, part of the embodiments of this invention. No further examples in this regard are provided herein because the interactions and transformations in a given medium that lead to the various forms of a given compound are known by any one of ordinary skill in the art.
Any formula given herein is also intended to represent unlabeled forms as well as isotopically labeled forms of the compounds. Isotopically labeled compounds have structures depicted by the formulas given herein except that one or more atoms are replaced by an atom having a selected atomic mass or mass number. Examples of isotopes that can be incorporated into compounds of the invention include isotopes of hydrogen, carbon, nitrogen, oxygen, phosphorus, fluorine, and chlorine, such as 2H, 3H, 11C, 13C, 14C, 15N, 18O, 17O, 31P, 32P, 35S, 18F, 36Cl, 125I, respectively. Such isotopically labeled compounds are useful in metabolic studies (preferably with 14C), reaction kinetic studies (with, for example 2H or 3H), detection or imaging techniques [such as positron emission tomography (PET) or single-photon emission computed tomography (SPECT)] including drug or substrate tissue distribution assays, or in radioactive treatment of patients. In particular, an 18F or 11C labeled compound may be particularly preferred for PET or an I123 for SPECT studies. Further, substitution with heavier isotopes such as deuterium (i.e., 2H) may afford certain therapeutic advantages resulting from greater metabolic stability, for example increased in vivo half-life or reduced dosage requirements. Isotopically labeled compounds of this invention and prodrugs thereof can generally be prepared by carrying out the procedures disclosed in the schemes or in the examples and preparations described below by substituting a readily available isotopically labeled reagent for a non-isotopically labeled reagent.
When referring to any formula given herein, the selection of a particular moiety from a list of possible species for a specified variable is not intended to define the same choice of the species for the variable appearing elsewhere. In other words, where a variable appears more than once, the choice of the species from a specified list is independent of the choice of the species for the same variable elsewhere in the formula, unless stated otherwise.
By way of a first example on substituent terminology, if substituent S1example is one of S1 and S2, and substituent S2example is one of S3 and S4, then these assignments refer to embodiments of this invention given according to the choices S1example is S1 and S2example is S3; S1example is S1 and S2example is S4; S1example is S2 and S2example is S3; S1example is S2 and S2example is S4; and equivalents of each one of such choices. The shorter terminology “S1example is one of S1 and S2, and S2example is one of S3 and S4” is accordingly used herein for the sake of brevity, but not by way of limitation. The foregoing first example on substituent terminology, which is stated in generic terms, is meant to illustrate the various substituent assignments described herein. The foregoing convention given herein for substituents extends, when applicable, to members such as R1, R2, R3, R4, A, Ra, Rb, Rc, Rd, Re, Rf, Rg, Rh, Ri, Rj, and Rk, and any other generic substituent symbol used herein.
Furthermore, when more than one assignment is given for any member or substituent, embodiments of this invention comprise the various groupings that can be made from the listed assignments, taken independently, and equivalents thereof. By way of a second example on substituent terminology, if it is herein described that substituent Sexample is one of S1, S2, and S3, this listing refers to embodiments of this invention for which Sexample is S1; Sexample is S2; Sexample is S3; Sexample is one of S1 and S2; Sexample is one of S1 and S3; Sexample is one of S2 and S3; Sexample is one of S1, S2 and S3; and Sexample is any equivalent of each one of these choices. The shorter terminology “Sexample is one of S1, S2, and S3” is accordingly used herein for the sake of brevity, but not by way of limitation. The foregoing second example on substituent terminology, which is stated in generic terms, is meant to illustrate the various substituent assignments described herein. The foregoing convention given herein for substituents extends, when applicable, to members such as R1, R2, R3, R4, A, Ra, Rb, Rc, Rd, Re, Rf, Rg, Rh, Ri, Rj, and Rk, and any other generic substituent symbol used herein.
The nomenclature “C−j” with j>i, when applied herein to a class of substituents, is meant to refer to embodiments of this invention for which each and every one of the number of carbon members, from i to j including i and j, is independently realized. By way of example, the term C1-3 refers independently to embodiments that have one carbon member (C1), embodiments that have two carbon members (C2), and embodiments that have three carbon members (C3).
The term Cn-malkyl refers to an aliphatic chain, whether straight or branched, with a total number N of carbon members in the chain that satisfies n<N<m, with m>n. Any disubstituent referred to herein is meant to encompass the various attachment possibilities when more than one of such possibilities are allowed. For example, reference to disubstituent -A-B—, where A B, refers herein to such disubstituent with A attached to a first substituted member and B attached to a second substituted member, and it also refers to such disubstituent with A attached to the second substituted member and B attached to the first substituted member.
According to the foregoing interpretive considerations on assignments and nomenclature, it is understood that explicit reference herein to a set implies, where chemically meaningful and unless indicated otherwise, independent reference to embodiments of such set, and reference to each and every one of the possible embodiments of subsets of the set referred to explicitly.

Compounds of Formula (I) and Formula (II) and pharmaceutically acceptable salts thereof are used, alone or in combination with one or more additional active ingredients, to formulate pharmaceutical compositions. A pharmaceutical composition therefore comprises an effective amount of at least one a compound of Formula (I) and Formula (II) or a pharmaceutically acceptable salt thereof.
The invention includes also pharmaceutically acceptable salts of the compounds of Formula (I) and Formula (II), preferably of those described above and of the specific compounds exemplified herein, and methods of treatment using such salts.
A “pharmaceutically acceptable salt” is intended to mean a salt of a free acid or base of a compound represented by Formula (I) and Formula (II), that is non-toxic, biologically tolerable, or otherwise biologically suitable for administration to the subject. See, generally, G. S. Paulekuhn, et al., “Trends in Active Pharmaceutical Ingredient Salt Selection based on Analysis of the Orange Book Database”, J. Med. Chem., 2007, 50:6665-72, S. M. Berge, et al., “Pharmaceutical Salts”, J Pharm Sci., 1977, 66:1-19, and Handbook of Pharmaceutical Salts, Properties, Selection, and Use, Stahl and Wermuth, Eds., Wiley-VCH and VHCA, Zurich, 2002. Examples of pharmaceutically acceptable salts are those that are pharmacologically effective and suitable for contact with the tissues of patients without undue toxicity, irritation, or allergic response. A compound of Formula (I) and Formula (II) may possess a sufficiently acidic group, a sufficiently basic group, or both types of functional groups, and accordingly react with a number of inorganic or organic bases, and inorganic and organic acids, to form a pharmaceutically acceptable salt.
Examples of pharmaceutically acceptable salts include sulfates, pyrosulfates, bisulfates, sulfites, bisulfites, phosphates, monohydrogen-phosphates, dihydrogenphosphates, metaphosphates, pyrophosphates, chlorides, bromides, iodides, acetates, propionates, decanoates, caprylates, acrylates, formates, isobutyrates, caproates, heptanoates, propiolates, oxalates, malonates, succinates, suberates, sebacates, fumarates, maleates, butyne-1,4-dioates, hexyne-1,6-dioates, benzoates, chlorobenzoates, methylbenzoates, dinitrobenzoates, hydroxybenzoates, methoxybenzoates, phthalates, sulfonates, xylenesulfonates, phenylacetates, phenylpropionates, phenylbutyrates, citrates, lactates, γ-hydroxybutyrates, glycolates, tartrates, methane-sulfonates, propanesulfonates, naphthalene-1-sulfonates, naphthalene-2-sulfonates, and mandelates.
When the compound of Formula (I) or Formula (II) contains a basic nitrogen, the desired pharmaceutically acceptable salt may be prepared by any suitable method available in the art, for example, treatment of the free base with an inorganic acid, such as hydrochloric acid, hydrobromic acid, sulfuric acid, sulfamic acid, nitric acid, boric acid, phosphoric acid, and the like, or with an organic acid, such as acetic acid, phenylacetic acid, propionic acid, stearic acid, lactic acid, ascorbic acid, maleic acid, hydroxymaleic acid, isethionic acid, succinic acid, valeric acid, fumaric acid, malonic acid, pyruvic acid, oxalic acid, glycolic acid, salicylic acid, oleic acid, palmitic acid, lauric acid, a pyranosidyl acid, such as glucuronic acid or galacturonic acid, an alpha-hydroxy acid, such as mandelic acid, citric acid, or tartaric acid, an amino acid, such as aspartic acid, glutaric acid/or glutamic acid, an aromatic acid, such as benzoic acid, 2-acetoxybenzoic acid, naphthoic acid, or cinnamic acid, a sulfonic acid, such as laurylsulfonic acid, p-toluenesulfonic acid, methanesulfonic acid, ethanesulfonic acid, any compatible mixture of acids such as those given as examples herein, and any other acid and mixture thereof that are regarded as equivalents or acceptable substitutes in light of the ordinary level of skill in this technology.
When the compound of Formula (I) or Formula (II) is an acid, such as a carboxylic acid or sulfonic acid, the desired pharmaceutically acceptable salt may be prepared by any suitable method, for example, treatment of the free acid with an inorganic or organic base, such as an amine (primary, secondary or tertiary), an alkali metal hydroxide, alkaline earth metal hydroxide, any compatible mixture of bases such as those given as examples herein, and any other base and mixture thereof that are regarded as equivalents or acceptable substitutes in light of the ordinary level of skill in this technology. Illustrative examples of suitable salts include organic salts derived from amino acids, such as N-methyl-D-glucamine, lysine, choline, glycine and arginine, ammonia, carbonates, bicarbonates, primary, secondary, and tertiary amines, and cyclic amines, such as tromethamine, benzylamines, pyrrolidines, piperidine, morpholine, and piperazine, and inorganic salts derived from sodium, calcium, potassium, magnesium, manganese, iron, copper, zinc, aluminum, and lithium.
The invention also relates to pharmaceutically acceptable prodrugs of the compounds of Formula (I) and Formula (II), and treatment methods employing such pharmaceutically acceptable prodrugs. The term “prodrug” means a precursor of a designated compound that, following administration to a subject, yields the compound in vivo via a chemical or physiological process such as solvolysis or enzymatic cleavage, or under physiological conditions (e.g., a prodrug on being brought to physiological pH is converted to the compound of Formula (I) or Formula (II)). A “pharmaceutically acceptable prodrug” is a prodrug that is non-toxic, biologically tolerable, and otherwise biologically suitable for administration to the subject. Illustrative procedures for the selection and preparation of suitable prodrug derivatives are described, for example, in “Design of Prodrugs”, ed. H. Bundgaard, Elsevier, 1985.
Exemplary prodrugs include compounds having an amino acid residue, or a polypeptide chain of two or more (e.g., two, three or four) amino acid residues, covalently joined through an amide or ester bond to a free amino, hydroxy, or carboxylic acid group of a compound of Formula (I) or Formula (II). Examples of amino acid residues include the twenty naturally occurring amino acids, commonly designated by three letter symbols, as well as 4-hydroxyproline, hydroxylysine, demosine, isodemosine, 3-methylhistidine, norvalin, beta-alanine, gamma-aminobutyric acid, citrulline homocysteine, homoserine, ornithine and methionine sulfone.
Additional types of prodrugs may be produced, for instance, by derivatizing free carboxyl groups of structures of Formula (I) or Formula (II) as amides or alkyl esters. Examples of amides include those derived from ammonia, primary C1-6alkyl amines and secondary di(C1-6alkyl) amines. Secondary amines include 5- or 6-membered heterocycloalkyl or heteroaryl ring moieties. Examples of amides include those that are derived from ammonia, C1-3alkyl primary amines, and di(C1-2alkyl)amines. Examples of esters of the invention include C1-7alkyl, C5-7cycloalkyl, phenyl, and phenyl(C1-6alkyl) esters. Preferred esters include methyl esters. Prodrugs may also be prepared by derivatizing free hydroxy groups using groups including hemisuccinates, phosphate esters, dimethylaminoacetates, and phosphoryloxymethyloxycarbonyls, following procedures such as those outlined in Fleisher et al., Adv. Drug Delivery Rev. 1996, 19, 115-130. Carbamate derivatives of hydroxy and amino groups may also yield prodrugs. Carbonate derivatives, sulfonate esters, and sulfate esters of hydroxy groups may also provide prodrugs. Derivatization of hydroxy groups as (acyloxy)methyl and (acyloxy)ethyl ethers, wherein the acyl group may be an alkyl ester, optionally substituted with one or more ether, amine, or carboxylic acid functionalities, or where the acyl group is an amino acid ester as described above, is also useful to yield prodrugs. Prodrugs of this type may be prepared as described in Robinson et al., J Med Chem. 1996, 39(1),10-18. Free amines can also be derivatized as amides, sulfonamides or phosphonamides. All of these prodrug moieties may incorporate groups including ether, amine, and carboxylic acid functionalities.
The present invention also relates to pharmaceutically active metabolites of the compounds of Formula (I) or Formula (II), which may also be used in the methods of the invention. A “pharmaceutically active metabolite” means a pharmacologically active product of metabolism in the body of a compound of Formula (I) or Formula (II) or salt thereof. Prodrugs and active metabolites of a compound may be determined using routine techniques known or available in the art. See, e.g., Bertolini, et al., J Med Chem. 1997, 40, 2011-2016; Shan, et al., J Pharm Sci. 1997, 86 (7), 765-767; Bagshawe, Drug Dev Res. 1995, 34, 220-230; Bodor, Adv Drug Res. 1984, 13, 224-331; Bundgaard, Design of Prodrugs (Elsevier Press, 1985); and Larsen, Design and Application of Prodrugs, Drug Design and Development (Krogsgaard-Larsen, et al., eds., Harwood Academic Publishers, 1991).
The compounds of Formula (I) or Formula (II) and their pharmaceutically acceptable salts, pharmaceutically acceptable prodrugs, and pharmaceutically active metabolites of the present invention are useful as modulators of the orexin receptor in the methods of the invention. As such modulators, the compounds may act as antagonists, agonists, or inverse agonists. The term “modulators” include both inhibitors and activators, where “inhibitors” refer to compounds that decrease, prevent, inactivate, desensitize or down-regulate orexin receptor expression or activity, and “activators” are compounds that increase, activate, facilitate, sensitize, or up-regulate orexin receptor expression or activity.
The term “treat” or “treating” as used herein is intended to refer to administration of an active agent or composition of the invention to a subject for the purpose of effecting a therapeutic benefit through modulation of orexin receptor activity. Treating includes reversing, ameliorating, alleviating, inhibiting the progress of, or lessening the severity of a disease, disorder, or condition, or one or more symptoms of such disease, disorder or condition mediated through modulation of orexin receptor activity. The term “subject” refers to a mammalian patient in need of such treatment, such as a human.
Accordingly, the invention relates to methods of using the compounds described herein to treat subjects diagnosed with or suffering from a disease, disorder, or condition mediated by orexin receptor activity, such as: disorders of the sleep-wake cycle, metabolic disorders, neurological disorders and other disorders (e.g., feeding, drinking, arousal, stress, addiction, metabolism and reproduction). Symptoms or disease states are intended to be included within the scope of “medical conditions, disorders, or diseases.”
Sleep disorders include, but are not limited to, sleep-wake transition disorders, insomnia, restless legs syndrome, jet-lag, disturbed sleep, and sleep disorders secondary to neurological disorders (e.g., manias, depressions, manic depression, schizophrenia, and pain syndromes (e.g., fibromyalgia, neuropathic).
Metabolic disorders include, but are not limited to, overweight or obesity and conditions related to overweight or obesity, such as insulin resistance, type II diabetes, hyperlipidemia, gallstones, angina, hypertension, breathlessness, tachycardia, infertility, sleep apnea, back and joint pain, varicose veins and osteoarthritis.
Neurological disorders include, but are not limited to, Parkinson's disease, Alzheimer's disease, Tourette's Syndrome, catatonia, anxiety, delirium and dementias.
Other disorders include, but are not limited to, ulcers, irritable bowel syndrome, diarrhea and gastroesophageal reflux.
In treatment methods according to the invention, an effective amount of a pharmaceutical agent according to the invention is administered to a subject suffering from or diagnosed as having such a disease, disorder, or condition. An “effective amount” means an amount or dose sufficient to generally bring about the desired therapeutic or prophylactic benefit in patients in need of such treatment for the designated disease, disorder, or condition. Effective amounts or doses of the compounds of the present invention may be ascertained by routine methods such as modeling, dose escalation studies or clinical trials, and by taking into consideration routine factors, e.g., the mode or route of administration or drug delivery, the pharmacokinetics of the compound, the severity and course of the disease, disorder, or condition, the subject's previous or ongoing therapy, the subject's health status and response to drugs, and the judgment of the treating physician. An example of a dose is in the range of from about 0.001 to about 200 mg of compound per kg of subject's body weight per day, preferably about 0.05 to 100 mg/kg/day, or about 1 to 35 mg/kg/day, in single or divided dosage units (e.g., BID, TID, QID). For a 70-kg human, an illustrative range for a suitable dosage amount is from about 0.05 to about 7 g/day, or about 0.2 to about 2.5 g/day.
Once improvement of the patient's disease, disorder, or condition has occurred, the dose may be adjusted for preventative or maintenance treatment. For example, the dosage or the frequency of administration, or both, may be reduced as a function of the symptoms, to a level at which the desired therapeutic or prophylactic effect is maintained. Of course, if symptoms have been alleviated to an appropriate level, treatment may cease. Patients may, however, require intermittent treatment on a long-term basis upon any recurrence of symptoms.
In addition, the active agents of the invention may be used in combination with additional active ingredients in the treatment of the above conditions. The additional active ingredients may be coadministered separately with an active agent of compounds of Formulas (I) and (II) or included with such an agent in a pharmaceutical composition according to the invention. In an exemplary embodiment, additional active ingredients are those that are known or discovered to be effective in the treatment of conditions, disorders, or diseases mediated by orexin activity, such as another orexin modulator or a compound active against another target associated with the particular condition, disorder, or disease. The combination may serve to increase efficacy (e.g., by including in the combination a compound potentiating the potency or effectiveness of an active agent according to the invention), decrease one or more side effects, or decrease the required dose of the active agent according to the invention.
The active agents of the invention are used, alone or in combination with one or more additional active ingredients, to formulate pharmaceutical compositions of the invention. A pharmaceutical composition of the invention comprises: (a) an effective amount of at least one active agent in accordance with the invention; and (b) a pharmaceutically acceptable excipient.
A “pharmaceutically acceptable excipient” refers to a substance that is non-toxic, biologically tolerable, and otherwise biologically suitable for administration to a subject, such as an inert substance, added to a pharmacological composition or otherwise used as a vehicle, carrier, or diluent to facilitate administration of an agent and that is compatible therewith. Examples of excipients include calcium carbonate, calcium phosphate, various sugars and types of starch, cellulose derivatives, gelatin, vegetable oils, and polyethylene glycols.
Delivery forms of the pharmaceutical compositions containing one or more dosage units of the active agents may be prepared using suitable pharmaceutical excipients and compounding techniques known or that become available to those skilled in the art. The compositions may be administered in the inventive methods by a suitable route of delivery, e.g., oral, parenteral, rectal, topical, or ocular routes, or by inhalation.
The preparation may be in the form of tablets, capsules, sachets, dragees, powders, granules, lozenges, powders for reconstitution, liquid preparations, or suppositories. Preferably, the compositions are formulated for intravenous infusion, topical administration, or oral administration.
For oral administration, the compounds of the invention can be provided in the form of tablets or capsules, or as a solution, emulsion, or suspension. To prepare the oral compositions, the compounds may be formulated to yield a dosage of, e.g., from about 0.05 to about 100 mg/kg daily, or from about 0.05 to about 35 mg/kg daily, or from about 0.1 to about 10 mg/kg daily. For example, a total daily dosage of about 5 mg to 5 g daily may be accomplished by dosing once, twice, three, or four times per day.
Oral tablets may include a compound according to the invention mixed with pharmaceutically acceptable excipients such as inert diluents, disintegrating agents, binding agents, lubricating agents, sweetening agents, flavoring agents, coloring agents and preservative agents. Suitable inert fillers include sodium and calcium carbonate, sodium and calcium phosphate, lactose, starch, sugar, glucose, methyl cellulose, magnesium stearate, mannitol, sorbitol, and the like. Exemplary liquid oral excipients include ethanol, glycerol, water, and the like. Starch, polyvinyl-pyrrolidone (PVP), sodium starch glycolate, microcrystalline cellulose, and alginic acid are suitable disintegrating agents. Binding agents may include starch and gelatin. The lubricating agent, if present, may be magnesium stearate, stearic acid or talc. If desired, the tablets may be coated with a material such as glyceryl monostearate or glyceryl distearate to delay absorption in the gastrointestinal tract, or may be coated with an enteric coating.
Capsules for oral administration include hard and soft gelatin capsules. To prepare hard gelatin capsules, compounds of the invention may be mixed with a solid, semi-solid, or liquid diluent. Soft gelatin capsules may be prepared by mixing the compound of the invention with water, an oil such as peanut oil or olive oil, liquid paraffin, a mixture of mono and di-glycerides of short chain fatty acids, polyethylene glycol 400, or propylene glycol.
Liquids for oral administration may be in the form of suspensions, solutions, emulsions or syrups or may be lyophilized or presented as a dry product for reconstitution with water or other suitable vehicle before use. Such liquid compositions may optionally contain: pharmaceutically-acceptable excipients such as suspending agents (for example, sorbitol, methyl cellulose, sodium alginate, gelatin, hydroxyethylcellulose, carboxymethylcellulose, aluminum stearate gel and the like); non-aqueous vehicles, e.g., oil (for example, almond oil or fractionated coconut oil), propylene glycol, ethyl alcohol, or water; preservatives (for example, methyl or propyl p-hydroxybenzoate or sorbic acid); wetting agents such as lecithin; and, if desired, flavoring or coloring agents.
The active agents of this invention may also be administered by non-oral routes. For example, the compositions may be formulated for rectal administration as a suppository. For parenteral use, including intravenous, intramuscular, intraperitoneal, or subcutaneous routes, the compounds of the invention may be provided in sterile aqueous solutions or suspensions, buffered to an appropriate pH and isotonicity or in parenterally acceptable oil. Suitable aqueous vehicles include Ringer's solution and isotonic sodium chloride. Such forms will be presented in unit-dose form such as ampules or disposable injection devices, in multi-dose forms such as vials from which the appropriate dose may be withdrawn, or in a solid form or pre-concentrate that can be used to prepare an injectable formulation. Illustrative infusion doses may range from about 1 to 1000 μg/kg/minute of compound, admixed with a pharmaceutical carrier over a period ranging from several minutes to several days.
For topical administration, the compounds may be mixed with a pharmaceutical carrier at a concentration of about 0.1% to about 10% of drug to vehicle. Another mode of administering the compounds of the invention may utilize a patch formulation to affect transdermal delivery.
Compounds of the invention may alternatively be administered in methods of this invention by inhalation, via the nasal or oral routes, e.g., in a spray formulation also containing a suitable carrier.
Exemplary compounds useful in methods of the invention will now be described by reference to the illustrative synthetic schemes for their general preparation below and the specific examples that follow. Artisans will recognize that, to obtain the various compounds herein, starting materials may be suitably selected so that the ultimately desired substituents will be carried through the reaction scheme with or without protection as appropriate to yield the desired product. Alternatively, it may be necessary or desirable to employ, in the place of the ultimately desired substituent, a suitable group that may be carried through the reaction scheme and replaced as appropriate with the desired substituent. Unless otherwise specified, the variables are as defined above in reference to Formula (I). Reactions may be performed between the melting point and the reflux temperature of the solvent, and preferably between 0° C. and the reflux temperature of the solvent. Reactions may be heated employing conventional heating or microwave heating. Reactions may also be conducted in sealed pressure vessels above the normal reflux temperature of the solvent.
Abbreviations and acronyms used herein include the following:
Intermediate compounds of formulae (Via) and (VIb) are readily prepared as outlined in Scheme A from a commercially available or synthetically accessible compound of formula (IV).

DCI in D2O, at temperatures ranging from 90° C. to 100° C. to provide deuterated pyrimidinols of formula (XXXI). Chlorination under standard chlorinating conditions provides chlorodeuteratedpyrimidine compounds of formula (XXXII).
Compounds of formula (I) may be converted to their corresponding salts using methods known to those skilled in the art. For example, amines of formula (I) may be treated with trifluoroacetic acid (TFA), HCl, maleic acid, or citric acid in a solvent such as diethyl ether (Et2O), CH2Cl2, tetrahydrofuran (THF), or methanol (MeOH) to provide the corresponding salt forms. In a particularly preferred embodiment the acid is HCl and the solvent is isopropanol.
Compounds prepared according to the schemes described above may be obtained as single enantiomers, diastereomers, or regioisomers, by enantio-, diastero-, or regiospecific synthesis, or by resolution. Compounds prepared according to the schemes above may alternately be obtained as racemic (1:1) or non-racemic (not 1:1) mixtures or as mixtures of diastereomers or regioisomers. Where racemic and non-racemic mixtures of enantiomers are obtained, single enantiomers may be isolated using conventional separation methods known to one skilled in the art, such as chiral chromatography, recrystallization, diastereomeric salt formation, derivatization into diastereomeric adducts, biotransformation, or enzymatic transformation. Where regioisomeric or diastereomeric mixtures are obtained, single isomers may be separated using conventional methods such as chromatography or crystallization.

Chemistry:
In obtaining the compounds described in the examples below and the corresponding analytical data, the following experimental and analytical protocols were followed unless otherwise indicated.
Unless otherwise stated, reaction mixtures were magnetically stirred at room temperature (rt) under a nitrogen atmosphere. Where solutions were “dried,” they were generally dried over a drying agent such as Na2SO4 or MgSO4.

During this time, in a separate 5 L jacketed reactor equipped with a mechanical stirrer and temperature probe were added toluene (600 mL), aqueous sodium carbonate (185.7 g, 1.75 mol in 1.6 L water), and 2-(4,6-dimethyl-pyrimidin-2-yl)-octahydro-pyrrolo[3,4-c]pyrrole*HOAc (Intermediate 23, 122 g, 438 mmol). This biphasic mixture was cooled to 0° C. After cooling to 0° C., the original slurry was poured through a filter and over the stirring biphasic mixture of amine and aqueous sodium carbonate. The mixture was allowed to warm to room temperature. After 2 h, additional 2-(4,6-dimethyl-pyrimidin-2-yl)-octahydro-pyrrolo[3,4-c]pyrrole*HOAc (4 g, 14 mmol) was added and the mixture was stirred for 30 additional minutes. At the end of this period, the layers were separated and 100 mL of methanol were added to the organic layer. The organic layer was dried over MgSO4, filtered, and concentrated to a white solid. This solid was taken up in ethanol (1.4 L) and warmed to 77° C. The mixture was then cooled to 55° C. and seeded with previously crystallized material. (Note: The seeds were generated from slurrying the initial product in 2-propanol at room temperature [100 mg/mL]). The mixture was cooled to room temperature at a rate of 5° C. per hour. After stirring at room temperature for 14 h, the mixture was filtered and dried to provide the final product as a white crystalline solid (136.84 g, 74%). 1H NMR (400 MHz, CDCl3): 7.88-7.78 (m, 1.78H), 7.75-7.69 (s, 1.22H), 7.51-7.43 (m, 1H), 7.17-7.11 (m, 1H), 6.30-6.28 (m, 1H), 4.03-3.48 (m, 7H), 3.29-3.21 (m, 1H), 3.15-2.92 (m, 2H), 2.30 (s, 6H).

Method B:
Step A: A one-piece EasyMax reactor was equipped with a mechanical stirred, a temperature probe, a reflux condenser and an NaOH scrubber. To the reactor was added 2-fluoro-6-triazol-2-yl benzoic acid (15.01 g, 72.5 mmol) and toluene (150.0 g), N,N-dimethylformamide (0.06 g, 0.26 mmol) was then added, the reaction was held at 20° C. prior to the addition of thionyl chloride (11.31 g, 94.1 mmol) via syringe pump. The reaction mixture was then heated to 50° C. over 15 minutes and then was stirred at that temperature for 1.5 hours. The mixture was then heated to 55° C. and 20.4 g of solvent were distilled in vacuo to give 139.4 g of acid chloride solution which was used as is in Step C below.
Step B. In a 500 mL jacketed reactor equipped with a mechanical stirrer, thermometer and reflux condenser was charged with 2-(4,6-dimethylpyrimidin-2-yl)octahydropyrrolo[3,4-c]pyrrole, bis-HCl salt (21.01 g, 72.1 mmol) and toluene (60.1 g) and the slurry was stirred at 0° C. Sodium carbonate (30.6 g, 288.7 mmol) was then separately dissolved in water (151.5 g) and then added to the slurry over 15 minutes to give the crude amine solution which was used directly in Step C.
Step C. To the crude amine solution from Step B in a 500 mL reactor held at 0° C. was added the crude acid chloride solution from Step 1 and the reaction was held at 0° C. for another 15 minutes, then heated to 30° C. over 30 minutes. During this time the product started to precipitate and the aqueous layer formed a slurry. The reaction was then cooled to 20° C. over 30 minutes and stirred at this temperature overnight. The mixture was then heated to 75° C. over 40 minutes and stirred for 35 minutes. Stirring was then stopped and after 30 minutes the aqueous layer was removed. To the organic layer was then added water (90.0 g) and the mixture was stirred for 20 minutes at 75° C., then the stirrer was again stopped. After 10 minutes the aqueous layer was removed. To the remaining organic layer was added water (90.0 g) and the mixture was again stirred at 75° C. for 15 minutes, before the stirrer was again stopped, and after 10 minutes the aqueous layer was again removed. Distillation of the remaining toluene solution was then performed (at 75° C., 350 mbar) to remove 70 mL of solvent. The remaining solution was then cooled to 50° C., and stirred for 20 minutes prior to the addition of Example 107 (0.04 g, seed crystals to start the crystallization). The reaction was then stirred at 50° C. for 1.5 hour, then the thin suspension was cooled to 30° C. over 1 hour then cooled to 0° C. over 1 hour. After 90 minutes the product was isolated by suction filtration, the filter cake was washed with cyclohexane (75 g), then washed with water (85.0 g) and the wet product cake was dried in vacuo at 55° C. overnight to give the title compound (25.21 g, 83%), Purity was assessed by HPLC (99.3%, 99.6%, and 99.3 area % (at 254, 235, and 280 nm, respectively).
Step D: The product of Step C (20.0 g, 48.9 mmol) was added to a one-piece EasyMax reactor and activated charcoal (Norit CN1, 2.00 g), ethanol (120.0 g) and 2-propanol (20.0 g) were then added. The mixture was heated to 85° C. over 30 minutes, then stirred for 45 minutes, then cooled to 75° C. over 15 minutes. The mixture was then filtered via a glass fiber filter, the filter was washed with 2-propanol (20.0 g) that was previously heated to 70° C., The filtrates were then placed into a 500 mL jacketed reactor equipped with a mechanical stirrer, reflux condenser and thermometer and heated to 85° C., stirred for 5 minutes, cooled to 55° C. over 20 minutes and after 10 minutes at 55° C. a suspension of Example 107 (0.02 g) in 2-propanol (0.20 g) was added. The resulting thin suspension was stirred at 55° C. for 1 hour, then was cooled to 45 over 1 hour and stirred for 30 minutes before it was cooled to 0° C. over 3 hours and was stirred at that temperature overnight. After 13 hours, the product was isolated by suction filtration, the filter cake was washed via the reactor with 2-propanol (40.0 g, at 10° C.) to provide the wet product cake which was dried in vacuo at 60° C. overnight to give the title compound (18.18 g, 91.3%) as a white to off-white crystalline solid. Purity was assessed by HPLC (99.7%, 99.8%, and 99.6 area % (at 254, 235, and 280 nm, respectively). Assays for residual solvents showed the following: ethanol 1089 ppm, 2-propanol 348 ppm, toluene 202 ppm, cyclohexane <20 ppm.

Human Orexin 1 Receptor Radioligand Binding Studies
Chinese ovary cells (CHO) stably expressing human orexin 1 receptor (Genebank accession number NM_001526) were grown to confluency in DMEM/F12 (Gibco, Cat #11039), 10% FBS, 1× Pen/Strep, 600 μg/mL G418 media on 150 cm2 tissue culture plates, washed with 5 mM EDTA in PBS (HyClone Dulbecco's Phosphate Buffered Saline 1× with Calcium and Magnesium, Cat # SH30264.01, hereafter referred to simply as PBS) and scraped into 50 ml tubes. After centrifugation (2K xG, 10 min at 4° C.), the supernatant was aspirated and the pellets frozen and stored at −80° C. Cells were resuspended in PBS in the presence of 1 tablet of protease inhibitor cocktail (Roche, Cat. #11836145001) per 50 mL. Each cell pellet from a 15 cm plate was resuspended in 10 mL, stored on ice, and vortexed for 45 sec prior to addition to the reactions. Competition binding experiments in 96 well polypropylene plates were performed using [3H]-SB674042 (Moravek Corporation, specific activity=35.3 Ci/mmol), diluted to a 10 nM concentration in PBS (4 nM final). Compounds were solubilized in 100% DMSO (Acros Organics, Cat. #61042-1000) and tested over a range of 7 concentrations (from 0.1 nM to 10 μM). The final concentration of DMSO in the reactions is equal to or less than 0.1%. Total and nonspecific binding was determined in the absence and presence of 10 μM (1-(6,8-difluoro-2-methylquinolin-4-yl)-3-[4-(dimethylamino)phenyl]urea, CAS Registry #288150-92-5). The total volume of each reaction is 200 μL (20 μL of diluted compounds, 80 μL of [3H]-SB674042 diluted in PBS and 100 μL of the cell suspension). Reactions were run for 60 min at room temperature and terminated by filtration through GF/C filter plates (PerkinElmer, Cat. #6005174) presoaked in 0.3% polyethylenimine using the cell harvester (PerkinElmer Filtermate). The plates were washed 3 times by aspirating 30 ml PBS through the plates. Plates were dried in 55° C. oven for 60 min, scintillation fluid was added, and the radioactivity was counted on a Topcount (Packard).
IC50 values (i.e. concentration of unlabelled compound required to compete for 50% of specific binding to the radioligand) were calculated using the GraphPad Prism software (GraphPad Prism Software Inc., San Diego, Calif.) with a fit to a sigmoidal dose-response curve. Apparent Ki values were calculated as Ki=IC50/(1+C/Kd), where C is concentration of radioligand and Kd=4 nM.
