Provided herein are isotopologues of certain haloaryl substituted aminopurine compounds, compositions comprising the isotopologues, methods of making the isotopologues, and methods of their use for treatment or prevention of diseases and conditions including, but not limited to, inflammatory diseases, autoimmune diseases, and cancers.
The connection between abnormal protein phosphorylation and the cause or consequence of diseases has been known for over 20 years. Accordingly, protein kinases have become a very important group of drug targets. See Cohen, Nature, 1:309-315 (2002). Various protein kinase inhibitors have been used clinically in the treatment of a wide variety of diseases, such as cancer and chronic inflammatory diseases, including diabetes and stroke. See Cohen, Eur. J. Biochem., 268:5001-5010 (2001).
Because protein kinases regulate nearly every cellular process, including metabolism, cell proliferation, cell differentiation, and cell survival, they are attractive targets for therapeutic intervention for various disease states. For example, cell-cycle control and angiogenesis, in which protein kinases play a pivotal role are cellular processes associated with numerous disease conditions such as but not limited to cancer, inflammatory diseases, abnormal angiogenesis and diseases related thereto, atherosclerosis, macular degeneration, diabetes, obesity, and pain.
Protein kinases have become attractive targets for the treatment of cancers. Fabbro et al., Pharmacology & Therapeutics 93:79-98 (2002). It has been proposed that the involvement of protein kinases in the development of human malignancies may occur by: (1) genomic rearrangements (e.g., BCR-ABL in chronic myelogenous leukemia), (2) mutations leading to constitutively active kinase activity, such as acute myelogenous leukemia and gastrointestinal tumors, (3) deregulation of kinase activity by activation of oncogenes or loss of tumor suppressor functions, such as in cancers with oncogenic RAS, (4) deregulation of kinase activity by over-expression, as in the case of EGFR and (5) ectopic expression of growth factors that can contribute to the development and maintenance of the neoplastic phenotype. Fabbro et al., Pharmacology & Therapeutics 93:79-98 (2002).
The elucidation of the intricacy of protein kinase pathways and the complexity of the relationship and interaction among and between the various protein kinases and kinase pathways highlights the importance of developing pharmaceutical agents capable of acting as protein kinase modulators, regulators or inhibitors that have beneficial activity on kinases or kinase pathways. Accordingly, there remains a need for new kinase modulators.

Compound 1 encompasses the following molecules, and mixtures thereof:
In one embodiment, the isotopologue is an isotopologue of
Certain embodiments encompass mixtures of isotopologues of Compound 1. Certain embodiments encompass methods of synthesizing, isolating, or characterizing the isotopologues of Compound 1. In certain embodiments, the isotopologues of Compound 1 are deuterium, carbon-13, nitrogen-15, or oxygen-18 enriched, or combinations thereof.
In certain embodiments, provided herein are pharmaceutical compositions and single unit dosage forms comprising one or more isotopologues of Compound 1. Certain embodiments provide methods for the treatment or prevention of particular diseases or disorders, which comprise administering to a patient a therapeutically or prophylactically effective amount of an isotopologue of Compound 1. In some embodiments, the isotopologues of Compound 1 are used in combination with one or more other therapeutic agents, as described herein.
The descriptions of the terminology provided below apply to the terms as used herein, unless otherwise specified.
As used herein “Compound 1” includes pharmaceutically acceptable salts, prodrugs, and solvates (e.g., hydrates) thereof.
The term “isotopic composition” refers to the amount of each isotope present for a given atom, and “natural isotopic composition” refers to the naturally occurring isotopic composition or abundance for a given atom. Atoms containing their natural isotopic composition may also be referred to herein as “non-enriched” atoms. Unless otherwise designated, the atoms of the compounds recited herein are meant to represent any stable isotope of that atom. For example, unless otherwise stated, when a position is designated specifically as “H” or “hydrogen,” the position is understood to have hydrogen at its natural isotopic composition.
The term “isotopically enriched” refers to an atom having an isotopic composition other than the natural isotopic composition of that atom. “Isotopically enriched” may also refer to a compound containing at least one atom having an isotopic composition other than the natural isotopic composition of that atom. As used herein, an “isotopologue” is an isotopically enriched compound.
The term “isotopic enrichment” refers to the percentage of incorporation of an amount of a specific isotope at a given atom in a molecule in the place of that atom's natural isotopic composition. For example, deuterium enrichment of 1% at a given position means that 1% of the molecules in a given sample contain deuterium at the specified position. Because the naturally occurring distribution of deuterium is about 0.0156%, about 0.0156% of molecules in a sample synthesized using non-enriched starting materials will have deuterium at a given position.
The term “isotopic enrichment factor” refers to the ratio between the isotopic composition and the natural isotopic composition of a specified isotope.
With regard to the compounds provided herein, when a particular atomic position is designated as having deuterium or “D,” it is understood that the abundance of deuterium at that position is substantially greater than the natural abundance of deuterium, which is about 0.0156%. A position designated as having deuterium typically has a minimum isotopic enrichment factor of, in particular embodiments, at least 100 (1.56% deuterium incorporation), at least 500 (7.8% deuterium incorporation), at least 1000 (15.6% deuterium incorporation), at least 2000 (31.2% deuterium incorporation), at least 3000 (46.8% deuterium incorporation), at least 3500 (54.6% deuterium incorporation), at least 4000 (62.4% deuterium incorporation), at least 4500 (70.2% deuterium incorporation), at least 5000 (78% deuterium incorporation), at least 5500 (85.8% deuterium incorporation), at least 6000 (93.6% deuterium incorporation), at least 6089.7 (95% deuterium incorporation), at least 6217.9 (97% deuterium incorporation), at least 6346.2 (99% deuterium incorporation), or at least 6378.2 (99.5% deuterium incorporation) at each designated deuterium atom.
The isotopic enrichment and isotopic enrichment factor of the compounds provided herein can be determined using conventional analytical methods known to one of ordinary skill in the art, including mass spectrometry and nuclear magnetic resonance spectroscopy.
As used herein, the term “pharmaceutically acceptable salt(s)” refers to a salt prepared from a pharmaceutically acceptable non-toxic acid or base including an inorganic acid and base and an organic acid and base. Suitable pharmaceutically acceptable base addition salts of the compounds described herein include, but are not limited to metallic salts made from aluminum, calcium, lithium, magnesium, potassium, sodium and zinc or organic salts made from lysine, N,N′-dibenzylethylenediamine, chloroprocaine, choline, diethanolamine, ethylenediamine, meglumine (N-methylglucamine) and procaine. Suitable non-toxic acids include, but are not limited to, inorganic and organic acids such as acetic, alginic, anthranilic, benzenesulfonic, benzoic, camphorsulfonic, citric, ethenesulfonic, formic, fumaric, furoic, galacturonic, gluconic, glucuronic, glutamic, glycolic, hydrobromic, hydrochloric, isethionic, lactic, maleic, malic, mandelic, methanesulfonic, mucic, nitric, pamoic, pantothenic, phenylacetic, phosphoric, propionic, salicylic, stearic, succinic, sulfanilic, sulfuric, tartaric acid, and p-toluenesulfonic acid. Specific non-toxic acids include hydrochloric, hydrobromic, maleic, phosphoric, sulfuric, and methanesulfonic acids. Examples of specific salts thus include hydrochloride and mesylate salts. Others are well-known in the art, see for example, Remington's Pharmaceutical Sciences, 18th eds., Mack Publishing, Easton Pa. (1990) or Remington: The Science and Practice of Pharmacy, 19th eds., Mack Publishing, Easton Pa. (1995).
As used herein and unless otherwise indicated, the term “solvate” means a compound as described herein, or a salt thereof, that further includes a stoichiometric or non-stoichiometric amount of a solvent bound by non-covalent intermolecular forces. In some embodiments, the solvate is a hydrate. As used herein and unless otherwise indicated, the term “hydrate” means a compound as described herein, or a salt thereof, that further includes a stoichiometric or non-stoichiometric amount of water bound by non-covalent intermolecular forces.
As used herein and unless otherwise indicated, the term “prodrug” means an derivative of a compound as described herein that can be hydrolyzed, oxidized, or otherwise reacted under biological conditions (in vitro or in vivo) to provide an active compound, particularly an isotopologue of Compound 1. Examples of prodrugs include, but are not limited to, derivatives and metabolites of a compound as described herein that include biohydrolyzable moieties such as biohydrolyzable amides, biohydrolyzable esters, biohydrolyzable carbamates, biohydrolyzable carbonates, biohydrolyzable ureides, and biohydrolyzable phosphate analogues.

The carboxylate esters are conveniently formed by esterifying any of the carboxylic acid moieties present on the molecule. Prodrugs can typically be prepared using well-known methods, such as those described by Burger's Medicinal Chemistry and Drug Discovery 6th ed. (Donald J. Abraham ed., 2001, Wiley) and Design and Application of Prodrugs (H. Bundgaard ed., 1985, Harwood Academic Publishers Gmfh).
As used herein and unless otherwise indicated, the term “stereoisomer” or “stereomerically pure” means one stereoisomer of a compound as described herein that is substantially free of other stereoisomers of that compound. A typical stereomerically pure compound comprises greater than about 80% by weight of one stereoisomer of the compound and less than about 20% by weight of other stereoisomers of the compound, greater than about 90% by weight of one stereoisomer of the compound and less than about 10% by weight of the other stereoisomers of the compound, greater than about 95% by weight of one stereoisomer of the compound and less than about 5% by weight of the other stereoisomers of the compound, or greater than about 97% by weight of one stereoisomer of the compound and less than about 3% by weight of the other stereoisomers of the compound.

The effective amount of a compound as described herein, for example in a pharmaceutical composition, may be at a level that will exercise the desired effect; for example, about 0.005 mg/kg of a subject's body weight to about 10 mg/kg of a subject's body weight in unit dosage for both oral and parenteral administration.
Provided herein are isotopically enriched compounds, including isotopically enriched Compound 1, synthetic intermediates thereof, and metabolites thereof.
Isotopic enrichment (e.g., deuteration) of pharmaceuticals to improve pharmacokinetics (“PK”), pharmacodynamics (“PD”), and toxicity profiles has been demonstrated previously with some classes of drugs. (See, e.g., Lijinsky et. al., Food Cosmet. Toxicol., 20: 393 (1982); Lijinsky et. al., J. Nat. Cancer Inst., 69: 1127 (1982); Mangold et. al., Mutation Res. 308: 33 (1994); Gordon et. al., Drug Metab. Dispos., 15: 589 (1987); Zello et. al., Metabolism, 43: 487 (1994); Gately et. al., J. Nucl. Med., 27: 388 (1986); Wade D, Chem. Biol. Interact. 117: 191 (1999)).
Without being limited by a particular theory, isotopic enrichment of a drug can be used, for example, to (1) reduce or eliminate unwanted metabolites, (2) increase the half-life of the parent drug, (3) decrease the number of doses needed to achieve a desired effect, (4) decrease the amount of a dose necessary to achieve a desired effect, (5) increase the formation of active metabolites, if any are formed, and/or (6) decrease the production of deleterious metabolites in specific tissues and/or create a more effective drug and/or a safer drug for combination therapy, whether the combination therapy is intentional or not.
Replacement of an atom for one of its isotopes may often result in a change in the reaction rate of a chemical reaction or an enzyme catalyzed reaction. This phenomenon is known as the Kinetic Isotope Effect (“KIE”). For example, if a C—H bond is broken during a rate-determining step in a chemical reaction (i.e. the step with the highest transition state energy), substitution of a deuterium for that hydrogen can cause a decrease in the reaction rate and the process may slow down. This phenomenon is known as the Deuterium Kinetic Isotope Effect (“DKIE”). (See, e.g, Foster et al., Adv. Drug Res., vol. 14, pp. 1-36 (1985); Kushner et al., Can. J. Physiol. Pharmacol., vol. 77, pp. 79-88 (1999)).
The magnitude of the DKIE can be expressed as the ratio between the rates of a given reaction in which a C—H bond is broken, and the same reaction where deuterium is substituted for hydrogen. The DKIE can range from about 1 (no isotope effect) to very large numbers, such as 50 or more, meaning that the reaction can be fifty, or more, times slower when deuterium is substituted for hydrogen. Without being limited by a particular theory, high DKIE values may be due in part to a phenomenon known as tunneling, which is a consequence of the uncertainty principle. Tunneling is ascribed to the small mass of a hydrogen atom, and occurs because transition states involving a proton can sometimes form in the absence of the required activation energy. Because deuterium has more mass than hydrogen, it statistically has a much lower probability of undergoing this phenomenon.
Tritium (“T”) is a radioactive isotope of hydrogen, used in research, fusion reactors, neutron generators and radiopharmaceuticals. Tritium is a hydrogen atom that has 2 neutrons in the nucleus and has an atomic weight close to 3. It occurs naturally in the environment in very low concentrations, most commonly found as T2O. Tritium decays slowly (half-life=12.3 years) and emits a low energy beta particle that cannot penetrate the outer layer of human skin. Internal exposure is the main hazard associated with this isotope, yet it must be ingested in large amounts to pose a significant health risk. As compared with deuterium, a lesser amount of tritium must be consumed before it reaches a hazardous level. Substitution of tritium (“T”) for hydrogen results in yet a stronger bond than deuterium and gives numerically larger isotope effects. Similarly, substitution of isotopes for other elements, including, but not limited to, 13C or 14C for carbon, 33S, 34S, or 36S for sulfur, 15N for nitrogen, and 17O or 18O for oxygen, may lead to a similar kinetic isotope effect.
The animal body expresses a variety of enzymes for the purpose of eliminating foreign substances, such as therapeutic agents, from its circulation system. Examples of such enzymes include the cytochrome P450 enzymes (“CYPs”), esterases, proteases, reductases, dehydrogenases, and monoamine oxidases, to react with and convert these foreign substances to more polar intermediates or metabolites for renal excretion. Some of the most common metabolic reactions of pharmaceutical compounds involve the oxidation of a carbon-hydrogen (C—H) bond to either a carbon-oxygen (C—O) or carbon-carbon (C—C) pi-bond. The resultant metabolites may be stable or unstable under physiological conditions, and can have substantially different pharmacokinetic, pharmacodynamic, and acute and long-term toxicity profiles relative to the parent compounds. For many drugs, such oxidations are rapid. These drugs therefore often require the administration of multiple or high daily doses.
Therefore, isotopic enrichment at certain positions of a compound provided herein may produce a detectable KIE that affects the pharmacokinetic, pharmacologic, and/or toxicological profiles of a compound provided herein in comparison with a similar compound having a natural isotopic composition. In one embodiment, the deuterium enrichment is performed on the site of C—H bond cleavage during metabolism.

The isotopologues of Compound 1 can be administered to a patient orally or parenterally in the conventional form of preparations, such as capsules, microcapsules, tablets, granules, powder, troches, pills, suppositories, injections, suspensions and syrups. Suitable formulations can be prepared by methods commonly employed using conventional, organic or inorganic additives, such as an excipient (e.g., sucrose, starch, mannitol, sorbitol, lactose, glucose, cellulose, talc, calcium phosphate or calcium carbonate), a binder (e.g., cellulose, methylcellulose, hydroxymethylcellulose, polypropylpyrrolidone, polyvinylpyrrolidone, gelatin, gum arabic, polyethyleneglycol, sucrose or starch), a disintegrator (e.g., starch, carboxymethylcellulose, hydroxypropylstarch, low substituted hydroxypropylcellulose, sodium bicarbonate, calcium phosphate or calcium citrate), a lubricant (e.g., magnesium stearate, light anhydrous silicic acid, talc or sodium lauryl sulfate), a flavoring agent (e.g., citric acid, menthol, glycine or orange powder), a preservative (e.g, sodium benzoate, sodium bisulfite, methylparaben or propylparaben), a stabilizer (e.g., citric acid, sodium citrate or acetic acid), a suspending agent (e.g., methylcellulose, polyvinyl pyrroliclone or aluminum stearate), a dispersing agent (e.g., hydroxypropylmethylcellulose), a diluent (e.g., water), and base wax (e.g., cocoa butter, white petrolatum or polyethylene glycol). The effective amount of the isotopologues of Compound 1 in the pharmaceutical composition may be at a level that will exercise the desired effect; for example, about 0.005 mg/kg of a patient's body weight to about 10 mg/kg of a patient's body weight in unit dosage for both oral and parenteral administration.
The dose of an isotopologue of Compound 1 to be administered to a patient is rather widely variable and can be subject to the judgment of a health-care practitioner. In general, the isotopologues of Compound 1 can be administered one to four times a day in a dose of about 0.005 mg/kg of a patient's body weight to about 10 mg/kg of a patient's body weight in a patient, but the above dosage may be properly varied depending on the age, body weight and medical condition of the patient and the type of administration. In one embodiment, the dose is about 0.01 mg/kg of a patient's body weight to about 5 mg/kg of a patient's body weight, about 0.05 mg/kg of a patient's body weight to about 1 mg/kg of a patient's body weight, about 0.1 mg/kg of a patient's body weight to about 0.75 mg/kg of a patient's body weight or about 0.25 mg/kg of a patient's body weight to about 0.5 mg/kg of a patient's body weight.

In a particular embodiment, doses of 600 mg or less are administered as a once daily dose and doses of more than 600 mg are administered twice daily in an amount equal to one half of the total daily dose.
An isotopologue of Compound 1 can be administered orally for reasons of convenience. In one embodiment, when administered orally, an isotopologue of Compound 1 is administered with a meal and water. In another embodiment, the isotopologue of Compound 1 is dispersed in water or juice (e.g., apple juice or orange juice) and administered orally as a suspension.
The isotopologue of Compound 1 can also be administered intradermally, intramuscularly, intraperitoneally, percutaneously, intravenously, subcutaneously, intranasally, epidurally, sublingually, intracerebrally, intravaginally, transdermally, rectally, mucosally, by inhalation, or topically to the ears, nose, eyes, or skin. The mode of administration is left to the discretion of the health-care practitioner, and can depend in-part upon the site of the medical condition.
In one embodiment, provided herein are capsules containing an isotopologue of Compound 1 without an additional carrier, excipient or vehicle.
In another embodiment, provided herein are compositions comprising an effective amount of an isotopologue of Compound 1 and a pharmaceutically acceptable carrier or vehicle, wherein a pharmaceutically acceptable carrier or vehicle can comprise an excipient, diluent, or a mixture thereof. In one embodiment, the composition is a pharmaceutical composition.
The compositions can be in the form of tablets, chewable tablets, capsules, solutions, parenteral solutions, troches, suppositories and suspensions and the like. Compositions can be formulated to contain a daily dose, or a convenient fraction of a daily dose, in a dosage unit, which may be a single tablet or capsule or convenient volume of a liquid. In one embodiment, the solutions are prepared from water-soluble salts, such as the hydrochloride salt. In general, all of the compositions are prepared according to known methods in pharmaceutical chemistry. Capsules can be prepared by mixing an isotopologue of Compound 1 with a suitable carrier or diluent and filling the proper amount of the mixture in capsules. The usual carriers and diluents include, but are not limited to, inert powdered substances such as starch of many different kinds, powdered cellulose, especially crystalline and microcrystalline cellulose, sugars such as fructose, mannitol and sucrose, grain flours and similar edible powders.
Tablets can be prepared by direct compression, by wet granulation, or by dry granulation. Their formulations usually incorporate diluents, binders, lubricants and disintegrators as well as the compound. Typical diluents include, for example, various types of starch, lactose, mannitol, kaolin, calcium phosphate or sulfate, inorganic salts such as sodium chloride and powdered sugar. Powdered cellulose derivatives are also useful. Typical tablet binders are substances such as starch, gelatin and sugars such as lactose, fructose, glucose and the like. Natural and synthetic gums are also convenient, including acacia, alginates, methylcellulose, polyvinylpyrrolidine and the like. Polyethylene glycol, ethylcellulose and waxes can also serve as binders.
A lubricant might be necessary in a tablet formulation to prevent the tablet and punches from sticking in the die. The lubricant can be chosen from such slippery solids as talc, magnesium and calcium stearate, stearic acid and hydrogenated vegetable oils. Tablet disintegrators are substances that swell when wetted to break up the tablet and release the compound. They include starches, clays, celluloses, algins and gums. More particularly, corn and potato starches, methylcellulose, agar, bentonite, wood cellulose, powdered natural sponge, cation-exchange resins, alginic acid, guar gum, citrus pulp and carboxymethyl cellulose, for example, can be used as well as sodium lauryl sulfate. Tablets can be coated with sugar as a flavor and sealant, or with film-forming protecting agents to modify the dissolution properties of the tablet. The compositions can also be formulated as chewable tablets, for example, by using substances such as mannitol in the formulation.
When it is desired to administer an isotopologue of Compound 1 as a suppository, typical bases can be used. Cocoa butter is a traditional suppository base, which can be modified by addition of waxes to raise its melting point slightly. Water-miscible suppository bases comprising, particularly, polyethylene glycols of various molecular weights are in wide use.
The effect of the isotopologue of Compound 1 can be delayed or prolonged by proper formulation. For example, a slowly soluble pellet of the isotopologue of Compound 1 can be prepared and incorporated in a tablet or capsule, or as a slow-release implantable device. The technique also includes making pellets of several different dissolution rates and filling capsules with a mixture of the pellets. Tablets or capsules can be coated with a film that resists dissolution for a predictable period of time. Even the parenteral preparations can be made long-acting, by dissolving or suspending the isotopologue of Compound 1 in oily or emulsified vehicles that allow it to disperse slowly in the serum.

The isoindoline portion of Compound 1 is deuterated by subjecting Compound 1 to conditions suitable for aromatic deuteration, which are known in the art, including for example, those disclosed in the following references, each of which are incorporated herein by reference in their entireties: U.S. Publication No. 2007/0255076; March, J. “Advanced Organic Chemistry, Reactions, Mechanisms, and Structure,” Fourth Ed., Wiley, New York, 1992; Larsen et al., J. Org. Chem., 43(18), 3602, 1978; Blake et al., J. Chem. Soc., Chem. Commun., 930, 1975; and references cited therein. For example, Compound 1 is treated with D2O over 5% Pt/C under hydrogen gas to provide an isotopologue of compound 1, as depicted in the scheme above.
The aminocyclohexanol portion of Compound 1 can be deuterated by oxidation of the hydroxyl moiety (with for example, pyridinium chlorochromate) followed by reduction in the presence of NaBD4, to afford the isotopologue of Compound 1 as shown above.
The following isotopically enriched starting materials can be used in the methods described herein to afford additional isotopologues of Compound 1.
Deuterated trifluoroaniline starting materials for deuterium enriched isotopologues of Compound 1 can be prepared by methods known in the art. For example, as shown in the scheme above, 1,3,5-trifluoro-2-isothiocyanatobenzene-2H can be prepared from commercially available 3-bromo-2,4,6-trifluoroaniline by hydrogenation with D2 in the presence of Pd/C, followed by conversion to the isothiocyanate derivative by treatment with carbon disulfide in the presence of a base such as TEA (J. Li et. al. Bioorganic & Medicinal Chemistry, 17(8): 3177-3188 (2009)).
Similarly, 2,4,6-trifluoro-3,5-diiodoaniline (W. Sander, et. al. J. Org. Chem. 72(3): 715-724 (2007)), can be bis-deuterated by treatment with D2 in the presence of Pd/C. As above, conversion to the isothiocyanate provides the precursor for the synthesis of the bis-deuterated isotopologue of Compound 1.
Deuterated halogenated nitropyrimidine starting materials can also be prepared using methods similar to those known in the art (e.g. Baasner, B. et al, J. Fluorine Chem. 45(3): 417-30 (1989)). For example, as shown above, 2,4,6-trichloro-5-nitropyrimidine can be treated with D2 in the presence of Pd/C to provide the deuterated starting material, to be used in the synthesis methods described herein.
Deuterated aminocychohexyl starting materials can be prepared using methods similar to those known in the art (e.g. Quirante, J. et al, J. Org. Chem. 67(7): 2323-2328 (2002)). For example, as shown above, tert-butyl benzyl(4-oxocyclohexyl)-carbamate can be reduced with NaBD4 to provide deuterated tert-butyl benzyl((1r,4r)-4-hydroxy-cyclohexyl)carbamate which, after deprotection of the tert-butyloxycarbonyl and benzyl protecting groups, can be incorporated by the synthesis methods described herein.
Isotopic enrichment may be confirmed may be confirmed and quantified by mass spectrometry and/or NMR, including, for example, proton-NMR; carbon-13NMR; or nitrogen-15NMR.
Isotopic enrichment may also be confirmed by single-crystal neutron diffraction. For example, the isotopic ratio at a particular hydrogen/deuterium position in a deuterated Compound 1 can be determined using single-crystal neutron diffraction. Neutron diffraction is advantageous because neutrons are scattered by the nucleus of an atom, therefore allowing for discrimination between isotopes, such as hydrogen and deuterium, which differ in the number of neutrons in the nucleus.
A single crystal of suitable size and quality comprising the deuterated Compound 1 is grown using standard methods of crystal growth. For single-crystal neutron diffraction experiments, crystals of several cubic millimeters are generally required for suitable data collection. A minimum size for a single crystal is typically about 1 cubic millimeter. Suitable single crystals are obtained by dissolving the deuterated Compound 1 in a solvent with appreciable solubility, then slowly evaporating or cooling the solution to yield crystals of suitable size and quality. Alternatively, suitable single crystals are obtained by dissolving the deuterated Compound 1 in a solvent with appreciable solubility, then slowly diffusing into the solution of antisolvent (i.e., a solvent in which the deuterated Compound 1 is not appreciably soluble) to yield crystals of suitable size and quality. These and other suitable methods of crystal growth are known in the art and are described, e.g., in George H. Stout & Lyle H. Jensen, X-Ray Structure Determination: A Practical Guide 74-92 (John Wiley & Sons, Inc. 2nd ed. 1989) (the entirety of which is incorporated herein).
After isolating a suitable single crystal comprising the deuterated Compound 1, the crystal is mounted in a neutron beam, neutron diffraction data is collected, and the crystal structure is solved and refined. Different neutron sources can be used, including steady-state sources and pulsed spallation sources. Examples of steady-state sources include the Grenoble ILL High Flux Reactor (Grenoble, France) and the Oak Ridge High Flux Isotope Reactor (Oak Ridge, Tenn.). Examples of pulsed spallation sources include ISIS, the spallation neutron source at Rutherford Appleton Laboratory (Oxfordshire, UK); the Intense Pulsed Neutron Source (IPNS) at Argonne National Laboratory (Argonne, Ill.), the Los Alamos Neutron Science Center (LANSCE) at Los Alamos National Laboratory (Los Alamos, N. Mex.), and the Neutron Science Laboratory (KENS) at KEK (Tsukuba, Ibaraki, Japan).
For a steady-state neutron source, four-circle diffractometer techniques are used with a monochromatic beam and a single detector, rotating the crystal and detector to measure each reflection sequentially. Diffractometer control software and step-scanning methods for intensity extraction can be adopted from routine four-circle X-ray diffractometry methods. One or more area detectors, including area detector arrays, may alternatively be used to increase the region of reciprocal space accessed in a single measurement. A broad band (white) beam used with an area detector allows for Laue or quasi-Laue diffraction with a stationary crystal and detector.
For a pulse source with a white neutron beam, time-of-flight Laue diffraction techniques are used, which allow for the determination of the velocity, energy, and wavelength of each neutron detected. This approach combines wavelength sorting with large area position-sensitive detectors, and allows for fixed scattering geometries (i.e., a stationary crystal and detector). Pulse source data collected in this fashion allows for rapid collection of data sets and good accuracy and precision in standard structural refinements. Additional details regarding steady-state and pulse source neutron diffraction experiments are well known in the art. See, e.g., Chick C. Wilson, Neutron Single Crystal Diffraction, 220 Z. Kristallogr. 385-98 (2005) (incorporated by reference herein in its entirety).
Crystal structure data, including particular isotopic ratios, are obtained from neutron diffraction data following routine structure solution and refinement processes. Structure solution is carried out using one of several methods, including direct methods and Patterson methods. For convenience, atomic coordinates from prior single crystal X-ray diffraction experiments may be used as a starting point for structure refinement using neutron diffraction data; this approach permits additional refinement of atomic positions, including hydrogen and deuterium positions. Refinement is conducted using full-matrix least-squares methods to achieve optimal agreement between the observed diffraction intensities and those calculated from the structural model. Ideally, full anisotropic refinement is carried out on all atoms, including the H/D atomic positions of interest. Data collection, structure solution and structure refinement methods, both for X-ray and neutron diffraction data, are well known in the art. See, e.g., Chick C. Wilson, Single Crystal Neutron Diffraction from Molecular Materials (World Scientific Publishing Co. 2000); George H. Stout & Lyle H. Jensen, X-Ray Structure Determination: A Practical Guide (John Wiley & Sons, Inc. 2nd ed. 1989) (both of which are incorporated herein in their entireties).
The isotopic ratio for a particular position on a deuterated Compound 1 is calculated by examining the neutron scattering cross sections for the H/D atomic position of interest. The scattering cross section is obtained as part of the refinement process discussed above. An example of determining the isotopic ratio for a partially deuterated compound is provided by G. A. Jeffrey et al., Neutron Diffraction Refinement of Partially Deuterated β-
