This invention provides advantageous isolated morphic forms of the Complement factor D inhibitors Compound 1 and Compound 2.
The complement system is a part of the innate immune system which does not adapt to changes over the course of the host's life, but is recruited and used by the adaptive immune system. For example, it assists, or complements, the ability of antibodies and phagocytic cells to clear pathogens. This sophisticated regulatory pathway allows rapid reaction to pathogenic organisms while protecting host cells from destruction. Over thirty proteins and protein fragments make up the complement system. These proteins act through opsonization (enhancing phagocytosis of antigens), chemotaxis (attracting macrophages and neutrophils), cell lysis (rupturing membranes of foreign cells), and agglutination (clustering and binding of pathogens together).
The complement system has three pathways: classical, alternative, and lectin. Complement Factor D plays an early and central role in activation of the alternative pathway of the complement cascade. Activation of the alternative complement pathway is initiated by spontaneous hydrolysis of a thioester bond within the C3 protein to produce C3(H2O), which associates with Factor B to form the C3(H2O)B complex. Complement Factor D acts to cleave Factor B within the C3(H2O)B complex to form Ba and Bb. The Bb fragment remains associated with C3(H2O) to form the alternative pathway C3 convertase C3(H2O)Bb. Additionally, C3b generated by any of the C3 convertases also associates with Factor B to form C3bB, which Factor D cleaves to generate the later stage alternative pathway C3 convertase C3bBb. This latter form of the alternative pathway C3 convertase may provide important downstream amplification within all three of the defined complement pathways, leading ultimately to the recruitment and assembly of additional factors in the complement cascade pathway, including the cleavage of C5 to C5a and C5b. C5b acts in the assembly of factors C6, C7, C8, and C9 into the membrane attack complex, which can destroy pathogenic cells by lysing the cell.
The dysfunction of or excessive activation of complement has been linked to certain autoimmune, inflammatory, and neurodegenerative diseases, as well as ischemia-reperfusion injury and cancer. For example, activation of the alternative pathway of the complement cascade contributes to the production of C3a and C5a, both potent anaphylatoxins, which also have roles in a number of inflammatory disorders. Therefore, in some instances, it is desirable to decrease the response of the complement pathway, including the alternative complement pathway. Some examples of disorders mediated by the complement pathway include age-related macular degeneration (AMD), paroxysmal nocturnal hemoglobinuria (PNH), multiple sclerosis, and rheumatoid arthritis.
Age-related macular degeneration (AMD) is a leading cause of vision loss in industrialized countries. Based on a number of genetic studies, there is evidence of the link between the complement cascade and macular degeneration. Individuals with mutations in the gene encoding complement Factor H have a fivefold increased risk of macular degeneration and individuals with mutations in other complement factor genes also have an increased risk of AMD. Individuals with mutant Factor H also have increased levels of C-reactive protein, a marker of inflammation. Without adequate functioning of Factor H, the alternative pathway of the complement cascade is overly activated leading to cellular damage.
Paroxysmal nocturnal hemoglobinuria (PNH) is a non-malignant, hematological disorder characterized by the expansion of hematopoietic stem cells and progeny mature blood cells that are deficient in some surface proteins. PNH erythrocytes are not capable of modulating their surface complement activation, which leads to the typical hallmark of PNH—the chronic activation of complement mediated intravascular anemia. Currently, only one product, the anti-C5 monoclonal antibody eculizumab, has been approved in the U.S. for treatment of PNH. However, many of the patients treated with eculizumab remain anemic, and many patients continue to require blood transfusions. In addition, treatment with eculizumab requires life-long intravenous injections.
Additional complement-mediated disorders include those classified under component 3 glomerulopathy (C3G). C3G is a recently defined entity comprised of dense deposit disease (DDD) and C3 glomerulonephritis (C3GN) which encompasses a population of chronic kidney diseases wherein elevated activity of the alternative complement pathway and terminal complement pathway results in glomerular deposits made solely of complement C3 and no immunoglobulin (Ig).
Immune-complex membranoproliferative glomerulonephritis (IC-MPGN) is a renal disease which shares many clinical, pathologic, genetic and laboratory features with C3G, and therefore can be considered a sister disease of C3G. In the majority of patients with IC-MPGN, an underlying disease or disorder—most commonly infections, autoimmune diseases, or monoclonal gammopathies—are identified to which the renal disease is secondary. Patients with idiopathic IC-MPGN can have low C3 and normal C4 levels, similar to those observed in C3G, as well as many of the same genetic or acquired factors that are associated with abnormal alternative pathway activity. Although there are current hypotheses suggesting that the majority of IC-MPGN is attributable to over activity of the classical pathway, those patients with a low C3 and a normal C4 are likely to have significant overactivity of the alternative pathway. IC-MPGN patients with a low C3 and a normal C4 may benefit from alternative pathway inhibition.
Other disorders that have been linked to the complement cascade include atypical hemolytic uremic syndrome (aHUS), hemolytic uremic syndrome (HUS), abdominal aortic aneurysm, hemodialysis complications, hemolytic anemia, or hemodialysis, neuromyelitis optica (NMO), myasthenia gravis (MG), fatty liver, nonalcoholic steatohepatitis (NASH), liver inflammation, cirrhosis, liver failure, dermatomyositis, and amyotrophic lateral sclerosis.
Factor D is an attractive target for inhibition or regulation of the complement cascade due to its early and essential role in the alternative complement pathway, and for its potential role in signal amplification within the classical and lectin complement pathways. Inhibition of Factor D effectively interrupts the pathway and attenuates the formation of the membrane attack complex.

A “patient” or “host” is a human or non-human animal, including, but not limited to, simian, avian, feline, canine, bovine, equine or porcine in need of medical treatment. Medical treatment can include treatment of an existing condition, such as a disease or disorder, or a prophylactic or diagnostic treatment. In a particular embodiment, the patient or host is a human patient. In an alternative embodiment, the patient such as a host is treated to prevent a disorder or disease described herein.
The term “isolated” as used herein refers to the material in substantially pure form. An isolated compound does not have another component that materially affects the properties of the compound. In particular embodiments, an isolated form is at least 60, 70, 80, 90, 95, 98 or 99% pure.
Pharmaceutical Preparations
The isolated morphic forms described herein can be administered in an effective amount to a host to treat any of the disorders described herein using any suitable approach which achieves the desired therapeutic result. The amount and timing of the isolated morphic forms administered will, of course, be dependent on the host being treated, the instructions of the supervising medical specialist, on the time course of the exposure, on the manner of administration, on the pharmacokinetic properties of the particular active compound, and on the judgment of the prescribing physician. Thus, because of host to host variability, the dosages given below are a guideline and the physician can titrate doses of the compound to achieve the treatment that the physician considers appropriate for the host. In considering the degree of treatment desired, the physician can balance a variety of factors such as age and weight of the host, presence of preexisting disease, as well as presence of other diseases.
An effective amount of a morphic form as described herein, or the morphic form described herein in combination or alternation with, or preceded by, concomitant with or followed by another active agent, can be used in an amount sufficient to (a) inhibit the progression of a disorder mediated by the complement pathway, including an inflammatory, immune, including an autoimmune, disorder or complement Factor D related disorder; (b) cause a regression of an inflammatory, immune, including an autoimmune, disorder or complement Factor D related disorder; (c) cause a cure of an inflammatory, immune, including an autoimmune, disorder or complement Factor D related disorder; or inhibit or prevent the development of an inflammatory, immune, including an autoimmune, disorder or complement Factor D related disorder. Accordingly, an effective amount of the morphic form or composition described herein will provide a sufficient amount of the active agent when administered to a patient to provide a clinical benefit.
The pharmaceutical composition may be formulated as any pharmaceutically useful form, e.g., a pill, a capsule, a tablet, a transdermal patch, a subcutaneous patch, a dry powder, an inhalation formulation, in a medical device, suppository, buccal, or sublingual formulation. Some dosage forms, such as tablets and capsules, are subdivided into suitably sized unit doses containing appropriate quantities of the active components, e.g., an effective amount to achieve the desired purpose.
The therapeutically effective dosage of the morphic forms described herein will be determined by the health care practitioner depending on the condition, size and age of the patient as well as the route of delivery.

Carriers include excipients and diluents and must be of sufficiently high purity and sufficiently low toxicity to render them suitable for administration to the patient being treated. The carrier can be inert or it can possess pharmaceutical benefits of its own. The amount of carrier employed in conjunction with the compound is sufficient to provide a practical quantity of material for administration per unit dose of the compound.
Classes of carriers include, but are not limited to binders, buffering agents, coloring agents, diluents, disintegrants, emulsifiers, flavorants, glidents, lubricants, preservatives, stabilizers, surfactants, tableting agents, and wetting agents. Some carriers may be listed in more than one class, for example vegetable oil may be used as a lubricant in some formulations and a diluent in others. Exemplary pharmaceutically acceptable carriers include sugars, starches, celluloses, powdered tragacanth, malt, gelatin; talc, and vegetable oils. Optional active agents may be included in a pharmaceutical composition, which do not substantially interfere with the activity of the compound of the present invention.
Depending on the intended mode of administration, the pharmaceutical compositions can be in the form of solid form or a semi-solid dosage form that the isolated morphic form is stable in, such as, for example, tablets, suppositories, pills, capsules, powders, or the like, preferably in unit dosage form suitable for single administration of a precise dosage. The compositions will include an effective amount of the selected drug in combination with a pharmaceutically acceptable carrier and, in addition, can include other pharmaceutical agents, adjuvants, diluents, buffers, and the like.
Thus, the compositions of the disclosure can be administered as pharmaceutical formulations including those suitable for oral (including buccal and sub-lingual), rectal, nasal, topical, pulmonary, vaginal administration or in a form suitable for administration by inhalation or insufflation. The preferred manner of administration is oral using a convenient daily dosage regimen which can be adjusted according to the degree of affliction. For solid compositions, conventional nontoxic solid carriers include, for example, pharmaceutical grades of mannitol, lactose, starch, magnesium stearate, sodium saccharin, talc, cellulose, glucose, sucrose, magnesium carbonate, and the like.

Tablets containing various excipients such as sodium citrate, calcium carbonate and calcium phosphate may be employed along with various disintegrants such as starch (e.g., potato or tapioca starch) and certain complex silicates, together with binding agents such as polyvinylpyrrolidone, sucrose, gelatin and acacia. Additionally, lubricating agents such as magnesium stearate, sodium lauryl sulfate, and talc are often very useful for tableting purposes. Solid compositions of a similar type may be employed as fillers in soft and hard-filled gelatin capsules.
Pharmaceutical formulations also are provided which provide a controlled release of a compound described herein, including through the use of a degradable polymer, as known in the art.
In one embodiment the additional therapeutic agent described in the Combination Section below is administered as a pharmaceutically acceptable salt, for example, a salt described below.
Thus, the term “salts” refers to the relatively non-toxic, inorganic and organic acid addition salts of the presently disclosed compounds. These salts can be prepared during the final isolation and purification of the compounds or by separately reacting the purified compound in its free base form with a suitable organic or inorganic acid and isolating the salt thus formed. Basic compounds are capable of forming a wide variety of different salts with various inorganic and organic acids. Acid addition salts of the basic compounds are prepared by contacting the free base form with a sufficient amount of the desired acid to produce the salt in the conventional manner. The free base form can be regenerated by contacting the salt form with a base and isolating the free base in the conventional manner. The free base forms may differ from their respective salt forms in certain physical properties such as solubility in polar solvents. Pharmaceutically acceptable base addition salts may be formed with metals or amines, such as alkali and alkaline earth metal hydroxides, or of organic amines. Examples of metals used as cations, include, but are not limited to, sodium, potassium, magnesium, calcium, and the like. Examples of suitable amines include, but are not limited to, N,N′-dibenzylethylenediamine, chloroprocaine, choline, diethanolamine, ethylenediamine, N-methylglucamine, and procaine. The base addition salts of acidic compounds are prepared by contacting the free acid form with a sufficient amount of the desired base to produce the salt in the conventional manner. The free acid form can be regenerated by contacting the salt form with an acid and isolating the free acid in a conventional manner. The free acid forms may differ from their respective salt forms somewhat in certain physical properties such as solubility in polar solvents.
Salts can be prepared from inorganic acids sulfate, pyrosulfate, bisulfate, sulfite, bisulfite, nitrate, phosphate, monohydrogenphosphate, dihydrogenphosphate, metaphosphate, pyrophosphate, chloride, bromide, iodide such as hydrochloric, nitric, phosphoric, sulfuric, hydrobromic, hydriodic, phosphorus, and the like.

Salts can also be prepared from organic acids, such as aliphatic mono- and dicarboxylic acids, phenyl-substituted alkanoic acids, hydroxy alkanoic acids, alkanedioic acids, aromatic acids, aliphatic and aromatic sulfonic acids, etc. and the like. Representative salts include acetate, propionate, caprylate, isobutyrate, oxalate, malonate, succinate, suberate, sebacate, fumarate, maleate, mandelate, benzoate, chlorobenzoate, methylbenzoate, dinitrobenzoate, phthalate, benzenesulfonate, toluenesulfonate, phenylacetate, citrate, lactate, maleate, tartrate, methanesulfonate, and the like. Pharmaceutically acceptable salts can include cations based on the alkali and alkaline earth metals, such as sodium, lithium, potassium, calcium, magnesium and the like, as well as non-toxic ammonium, quaternary ammonium, and amine cations including, but not limited to, ammonium, tetramethylammonium, tetraethylammonium, methylamine, dimethylamine, trimethylamine, triethylamine, ethylamine, and the like. Also contemplated are the salts of amino acids such as arginate, gluconate, galacturonate, and the like. See, for example, Berge et al., J. Pharm. Sci., 1977, 66, 1-19, which is incorporated herein by reference.
Formulations suitable for rectal administration are typically presented as unit dose suppositories. These may be prepared by admixing the active disclosed compound with one or more conventional solid carriers, for example, cocoa butter, and then shaping the resulting mixture.

Carriers which may be used include petroleum jelly, lanoline, polyethylene glycols, alcohols, transdermal enhancers, and combinations of two or more thereof.
Formulations suitable for transdermal administration may be presented as discrete patches adapted to remain in intimate contact with the epidermis of the recipient for a prolonged period of time. In one embodiment, microneedle patches or devices are provided for delivery of drugs across or into biological tissue, particularly the skin. The microneedle patches or devices permit drug delivery at clinically relevant rates across or into skin or other tissue barriers, with minimal or no damage, pain, or irritation to the tissue.
Formulations suitable for administration to the lungs can be delivered by a wide range of passive breath driven and active power driven single/-multiple dose dry powder inhalers (DPI). The devices most commonly used for respiratory delivery include nebulizers, metered-dose inhalers, and dry powder inhalers. Several types of nebulizers are available, including jet nebulizers, ultrasonic nebulizers, and vibrating mesh nebulizers. Selection of a suitable lung delivery device depends on parameters, such as nature of the drug and its formulation, the site of action, and pathophysiology of the lung.

In an additional alternative embodiment, a morphic form or composition as described herein is used in the treatment of an autoimmune disorder.
The complement pathway enhances the ability of antibodies and phagocytic cells to clear microbes and damaged cells from the body. It is part of the innate immune system and in healthy individuals is an essential process. Inhibiting the complement pathway will decrease the body's immune system response. Therefore, it is an object of the present invention to treat autoimmune disorders by administering an effective does of a morphic form or composition as described herein to a subject in need thereof.
In one embodiment the autoimmune disorder is caused by activity of the complement system. In one embodiment the autoimmune disorder is caused by activity of the alternative complement pathway. In one embodiment the autoimmune disorder is caused by activity of the classical complement pathway. In another embodiment the autoimmune disorder is caused by a mechanism of action that is not directly related to the complement system, such as the over-proliferation of T-lymphocytes or the over-production of cytokines.
Non-limiting examples of autoimmune disorders include: lupus, allograft rejection, autoimmune thyroid diseases (such as Graves' disease and Hashimoto's thyroiditis), autoimmune uveoretinitis, giant cell arteritis, inflammatory bowel diseases (including Crohn's disease, ulcerative colitis, regional enteritis, granulomatous enteritis, distal ileitis, regional ileitis, and terminal ileitis), diabetes, multiple sclerosis, pernicious anemia, psoriasis, rheumatoid arthritis, sarcoidosis, and scleroderma.
In one embodiment, a morphic form or composition as described herein is used in the treatment of lupus. Non-limiting examples of lupus include lupus erythematosus, cutaneous lupus, discoid lupus erythematosus, chilblain lupus erythematosus, or lupus erythematosus-lichen planus overlap syndrome.
Lupus erythematosus is a general category of disease that includes both systemic and cutaneous disorders. The systemic form of the disease can have cutaneous as well as systemic manifestations. However, there are also forms of the disease that are only cutaneous without systemic involvement. For example, SLE is an inflammatory disorder of unknown etiology that occurs predominantly in women, and is characterized by articular symptoms, butterfly erythema, recurrent pleurisy, pericarditis, generalized adenopathy, splenomegaly, as well as CNS involvement and progressive renal failure. The sera of most patients (over 98%) contain antinuclear antibodies, including anti-DNA antibodies. High titers of anti-DNA antibodies are essentially specific for SLE. Conventional treatment for this disease has been the administration of corticosteroids or immunosuppressants.
There are three forms of cutaneous lupus: chronic cutaneous lupus (also known as discoid lupus erythematosus or DLE), subacute cutaneous lupus, and acute cutaneous lupus. DLE is a disfiguring chronic disorder primarily affecting the skin with sharply circumscribed macules and plaques that display erythema, follicular plugging, scales, telangiectasia and atrophy. The condition is often precipitated by sun exposure, and the early lesions are erythematous, round scaling papules that are 5 to 10 mm in diameter and display follicular plugging. DLE lesions appear most commonly on the cheeks, nose, scalp, and ears, but they may also be generalized over the upper portion of the trunk, extensor surfaces of the extremities, and on the mucous membranes of the mouth. If left untreated, the central lesion atrophies and leaves a scar. Unlike SLE, antibodies against double-stranded DNA (e.g., DNA-binding test) are almost invariably absent in DLE.
Multiple Sclerosis is an autoimmune demyelinating disorder that is believed to be T lymphocyte dependent. MS generally exhibits a relapsing-remitting course or a chronic progressive course. The etiology of MS is unknown, however, viral infections, genetic predisposition, environment, and autoimmunity all appear to contribute to the disorder. Lesions in MS patients contain infiltrates of predominantly T lymphocyte mediated microglial cells and infiltrating macrophages. CD4+ T lymphocytes are the predominant cell type present at these lesions. The hallmark of the MS lesion is plaque, an area of demyelination sharply demarcated from the usual white matter seen in Mill scans. Histological appearance of MS plaques varies with different stages of the disease. In active lesions, the blood-brain barrier is damaged, thereby permitting extravasation of serum proteins into extracellular spaces. Inflammatory cells can be seen in perivascular cuffs and throughout white matter. CD4+ T-cells, especially Th1, accumulate around postcapillary venules at the edge of the plaque and are also scattered in the white matter. In active lesions, up-regulation of adhesion molecules and markers of lymphocyte and monocyte activation, such as IL2-R and CD26 have also been observed. Demyelination in active lesions is not accompanied by destruction of oligodendrocytes. In contrast, during chronic phases of the disease, lesions are characterized by a loss of oligodendrocytes and hence, the presence of myelin oligodendrocyte glycoprotein (MOG) antibodies in the blood.
Diabetes can refer to either type 1 or type 2 diabetes. In one embodiment a morphic form or composition as described herein is provided at an effective dose to treat a patient with type 1 diabetes. In one embodiment a morphic form or composition as described herein is provided at an effective dose to treat a patient with type 2 diabetes. Type 1 diabetes is an autoimmune disease. An autoimmune disease results when the body's system for fighting infection (the immune system) attacks a part of the body. In the case of diabetes type 1, the pancreas then produces little or no insulin.

In one embodiment, a morphic form or composition as described herein is administered in combination or alteration with an omega-3 fatty acid or a peroxisome proliferator-activated receptor (PPARs) agonist. Omega-3 fatty acids are known to reduce serum triglycerides by inhibiting DGAT and by stimulating peroxisomal and mitochondrial beta oxidation. Two omega-3 fatty acids, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), have been found to have high affinity for both PPAR-alpha and PPAR-gamma. Marine oils, e.g., fish oils, are a good source of EPA and DHA, which have been found to regulate lipid metabolism. Omega-3 fatty acids have been found to have beneficial effects on the risk factors for cardiovascular diseases, especially mild hypertension, hypertriglyceridemia and on the coagulation factor VII phospholipid complex activity. Omega-3 fatty acids lower serum triglycerides, increase serum HDL-cholesterol, lower systolic and diastolic blood pressure and the pulse rate, and lower the activity of the blood coagulation factor VII-phospholipid complex. Further, omega-3 fatty acids seem to be well tolerated, without giving rise to any severe side effects. One such form of omega-3 fatty acid is a concentrate of omega-3, long chain, polyunsaturated fatty acids from fish oil containing DHA and EPA and is sold under the trademark Omacor®. Such a form of omega-3 fatty acid is described, for example, in U.S. Pat. Nos. 5,502,077, 5,656,667 and 5,698,594, the disclosures of which are incorporated herein by reference.
Peroxisome proliferator-activated receptors (PPARs) are members of the nuclear hormone receptor superfamily ligand-activated transcription factors that are related to retinoid, steroid and thyroid hormone receptors. There are three distinct PPAR subtypes that are the products of different genes and are commonly designated PPAR-alpha, PPAR-beta/delta (or merely, delta) and PPAR-gamma. General classes of pharmacological agents that stimulate peroxisomal activity are known as PPAR agonists, e.g., PPAR-alpha agonists, PPAR-gamma agonists and PPAR-delta agonists. Some pharmacological agents are combinations of PPAR agonists, such as alpha/gamma agonists, etc., and some other pharmacological agents have dual agonist/antagonist activity. Fibrates such as fenofibrate, bezafibrate, clofibrate and gemfibrozil, are PPAR-alpha agonists and are used in patients to decrease lipoproteins rich in triglycerides, to increase HDL and to decrease atherogenic-dense LDL. Fibrates are typically orally administered to such patients. Fenofibrate or 2-[4-(4-chlorobenzoyl)phenoxy]-2-methyl-propanoic acid, 1-methylethyl ester, has been known for many years as a medicinally active principle because of its efficacy in lowering blood triglyceride and cholesterol levels.

Synthesis of Compound 1 and Compound 2
Compound 1, for example, can be synthesized by the procedure disclosed in PCT Application WO2015130795 and Compound 2, for example, can be synthesized by the procedure disclosed in PCT Application WO2017035353. An alternative synthesis of Compound 1 is shown below in Scheme 1 and an alternative synthesis of Compound 2 is shown below in Schemes 2-7.
In the synthesis of Compound 1, intermediate 9 was synthesized from intermediate 6 via a one-pot palladium-catalyzed Miyaura borylation/Suzuki cross-coupling reaction. 4-Bromo-2-methylpyrimidine (7) was reacted with bis(pinacolato)diboron to afford boronate ester 8. In the presence of catalyst Pd(ddpf)Cl2, intermediate 6 underwent a Suzuki reaction with boronate ester 8 to generate the coupled product, intermediate 9. Similarly, in the synthesis of Compound 2, intermediate 12 was synthesized from intermediate 11 using a one-pot Miyaura borylation/Suzuki coupling.
This one-pot Miyaura borylation/Suzuki coupling can be conducted between bromine-containing reagents, chloride-containing reagents, iodide-containing reagents, organotriflate-containing reagents, or any combination thereof. As described in Molander et al. (Journal of Organic Chemistry, 2012, 72, 8678-8688), the reaction can also be conducted with alternative Suzuki catalysts including, but not limited to, XPhos-Pd-G1, XPhos-Pd-G2, XPhos, or CataCXium A as defined in Molander et al. In one embodiment, the reaction is conducted with Suzuki catalysts XPhos-Pd-G1 and XPhos or XPhos-Pd-G2 and XPhos. In addition to bis(pinacolato)diboron, the borylation reagent can also be selected from, but not limited to, pinacolborane or bis-boronic acid.
Step 1: Synthesis of tert-Butyl (2S,4R)-2-((6-bromopyridin-2-yl)carbamoyl) fluoropyrrolidine-1-carboxylate (3): N-Boc-trans-4-Fluoro-L-proline (50.8 kg) was added to DCM (1000 L) in a glass-lined reactor under an atmosphere of nitrogen. The reaction mixture was cooled to 0±5° C. and N-methylimidazole (44.7 kg) was added while maintaining the temperature at 0±5° C. Methanesulfonyl chloride (29.97 kg) was slowly added to the reaction mixture followed by the addition of 2-amino-6-bromopyridine (2). The reaction temperature was warmed to room temperature and stirred for 12 h. The reaction was monitored by HPLC. After completion of the reaction water (2,000 kg) was added, the reaction was stirred and the DCM layer separated. The aqueous layer was once more extracted with DCM (1000 L). The combined DCM layer was washed in succession with dilute HCl, aqueous NaHCO3 and brine. The DCM extract was evaporated to dryness and tert-butyl (2S,4R)-2-((6-bromopyridin-2-yl)carbamoyl)-4-fluoropyrrolidine-1-carboxylate (3) was isolated using DCM heptane mixture and dried. Yield, 71.76 Kg (84.86%))
Step 2: Synthesis of (2S,4R)—N-(6-Bromopyridin-2-yl)-4-fluoropyrrolidine-2-carboxamide (4): To a solution 4M HCl/Dioxane (168 kg) was added intermediate 3 (40 kg) at 25±5° C. under an atmosphere of nitrogen and the reaction was stirred for 1 h.

The solubility of amorphous Compound 1 was estimated in 14 solvents to facilitate the solvent selection for the crystallization study. The solubility of Compound 1 was visually estimated at room temperature (RT; ˜23° C.) by dosing small aliquots of solvent into a fixed amount of solid (˜10 mg) until the dissolution point or a maximum volume (1.7 mL) was reached.
The solubility data are shown in Table 1 and indicate that amorphous Compound 1 is very highly soluble in DMSO (>452 mg/mL) and in most organic solvents including acetone (121-484 mg/mL). It is also highly soluble in methanol (48-96 mg/mL), but poorly soluble in heptane (<6 mg/mL), MTBE (<6 mg/mL) and water (<6 mg/mL).
The samples were processed by thermocycling the suspensions overnight between 40 and 5° C. Solutions were placed in a freezer overnight to induce nucleation, and subsequently evaporated to dryness at room temperature over one week. The results are shown in Table 2 and further discussed in Example 3.

Solvent Selection
The crystallization study involved a total of 24 solvent systems. The solubility data from Example 2 was utilized to create a diverse set of neat and binary solvent mixtures to target a solubility of 5-100 mg/mL. Where applicable, the composition of binary mixtures was varied during the course of crystallization to achieve various levels of supersaturation to encourage crystallization. In addition, aqueous mixtures were employed to probe for the formation of hydrates.
Sample Preparation
Samples were prepared by adding ˜15 mg of amorphous Compound 1 to 2 mL vials containing a tumble-stir disk. Solvents were added with volumes ranging from 250 μL to 500 μL (experiment dependent).
Crystallization Modes
The crystallization studies were comprised of the following crystallization modes:
Polarized-Light microscopy (PLM) was chosen as the primary method for crystallinity assessment of samples produced from the crystallization study. Powder X-Ray Diffraction (PXRD) was employed to confirm the crystallinity and to obtain the solid-state fingerprint, which was subsequently used to classify the samples into groups.
For PLM, the photomicrographs were collected using Olympus BX60 polarized-light microscope equipped with Olympus DP70 camera.
PXRD diffractograms were acquired using PANalytical X'Pert Pro diffractometer on Si zero-background wafers. All diffractograms were collected using a Cu Kα (45 kV/40 mA) radiation and a step size of 0.02° 2θ and X'celerator™ RTMS (Real Time Multi-Strip) detector. Nickel filter was used to reduce unwanted radiation, unless noted otherwise. Configuration on the incidental beam side: fixed divergence slit (¼ deg), 0.04 rad soller slits, anti-scatter slit (¼ deg), and 10 mm beam mask. Configuration on the diffracted beam side: fixed divergence slit (¼ deg) and 0.04 rad soller slit.

Step 2D: [(2S)-5-oxopyrrolidin-2-yl]methyl benzoate (23 g, 104.908 mmol, 1 equiv.), 4-dimethylaminopyridine (6.408 g, 52.454 mmol, 0.5 equiv.) in dichloromethane (230 mL, 0.456 M, 10 Vols) was cooled to 5° C. and di-tert-butyl dicarbonate (34.344 g, 36.152 mL, 157.362 mmol, 1.5 equiv.) was added. The reaction was stirred overnight at room temperature. The solvent was removed from the reaction mixture and heptane (100 mL) was added. The solution was stirred and the supernatant was decanted. The solid was dissolved in CH2Cl2 and washed with 1N HCl to remove DMAP. The DCM solution was evaporated to dryness, titurated with heptane (70 mL) and the solid filtered to afford tert-butyl (2S)-2-[(benzoyloxy)methyl]-5-oxopyrrolidine-1-carboxylate (35, 20.2 g, 63.252 mmol, Yield 99.053%)
Step 3D and 4D: Brederek reagent was added twice to intermediate 35 (25 g) to yield 28.4 g (97%) of product that was subjected to hydrogenation conditions (overnight reaction in IPA at 50° C.). This resulted in 11.6 g (87% yield) of intermediate 36 after chromatographic purification. The material was solid and can be crystallized if needed.
Step 5D: To a stirred solution of tert-butyl (5S)-5-[(benzoyloxy)methyl]-3-methyl-2-oxopyrrolidine-1-carboxylate (36, 5 g, 14.998 mmol, 1 equiv.) in tetrahydrofuran (75 mL, 0.2 M, 15 Vols) was added lithiumtriethylborohydride (1.748 g, 16.497 mL, 16.497 mmol, 1.1 equiv.) at −78° C. under argon. The reaction mixture was stirred at −78° C. for 20-30 minutes and then quenched with a saturated NaHCO3 solution at −78 to −70° C. The reaction mixture was warmed to −20° C. 30% hydrogen peroxide (5.612 g, 5.055 mL, 49.492 mmol, 3.3 equiv.) was added before further warming up to 0° C. over 15-20 minutes. The aqueous phase was extracted with AcOEt/saturated aqueous NaCl and the organic phase was washed with saturated aqueous NaCl. The aqueous layer was extracted again with CH2Cl2 twice and all organic layers were combined and concentrated. The residue was dissolved in CH2Cl2 and the aqueous layer was extracted three times with CH2Cl2, dried and concentrated to afford crude product, tert-butyl (5S)-5-[(benzoyloxy)methyl]-2-hydroxy-3-methylpyrrolidine-1-carboxylate (5.2 g). This crude material was used in the next step.
Step 6D: tert-butyl (5S)-5-[(benzoyloxy)methyl]-2-hydroxy-3-methylpyrrolidine-1-carboxylate (5.03 g, 14.997 mmol, 1 equiv.) and p-toluenesulfonic acid monohydrate (0.029 g, 0.15 mmol, 0.01 equiv.) were heated in toluene (50.3 mL, 0.298 M, 10 Vols) for 2 hours at 70° C. The reaction was cooled, washed with saturated aqueous NaHCO3, dried and evaporated. The crude material was purified by chromatography over silica gel (10% EtOAc/hexane) to afford 3.5 g of olefin 23.
Step 1E: Intermediate 31 (10 kg) and intermediate 30 (7.4 kg) were dissolved in DCM/pyridine and cooled to 0±5° C. Phosphorousoxy chloride (7 kg) was added to the mixture while maintaining the reaction temperature. After the reaction was complete, water was added carefully and the reaction was allowed to warm to room temperature. The aqueous layer was extracted with DCM and the combined DCM layers were washed with dilute HCl and water, dried over anhydrous sodium sulfate and evaporated to dryness. Heptane was added and evaporated and the residue triturated with 5% ethylacetate/heptane. The solid was filtered and dried to afford intermediate 32 (Yield 11.4 kg).
Step 2E: Intermediate 32 (5 kg) was added to 4M HCl/dioxane (21 kg) and the reaction was stirred at room temperature. After completion, the reaction was diluted with DCM and carefully washed with aqueous NaHCO3. The DCM layer was washed with water and evaporated to dryness. The product was crystallized from DCM/heptane to afford intermediate 33 (Yield 3.8 kg).
To a solution of intermediate 16 (2.2 kg) and intermediate 33 (2.03 kg) in DMF at 5±5° C. was added N,N-diispropylethylamine (6.6 kg). TBTU (2.97 kg) was added while maintaining the temperature of the reaction at 5±5° C. The reaction was warmed to room temperature and stirred for 4-8 hours. The reaction was diluted with water and the resulting solid formed was collected by centrifugation. The solid was washed with water two times and then dissolved in DCM and treated with siliabondthiol resin and activated charcoal to remove Pd based impurities. The resin and charcoal were removed by filtration and washed with MeOH/DCM. The filtrates were evaporated to dryness and the reside purified by chromatography over silica gel using methanol/DCM. The pure fractions were combined and evaporated to dryness. The residue was crystallized from IPA/heptane to afford Compounds 2 Form I (Yield, 1.84 kg).
A series of experiments were conducted to investigate the polymorphic landscape of Compound 2 (Table 7). A wide variety of solvents/solvent systems were utilized.
Attempts at melting the material were unsuccessful. Compound 2 discolored prior to becoming a uniform liquid phase indicating that decomposition may have occurred.
A number of crash precipitation (CP) experiments were carried out. When water or heptane was used as anti-solvents, solids tended to be generated from solution. A number of these experiments generated extremely small quantities of solids that were not characterized. Only Form 1 and disordered materials were generated from the experiments. When a solvent other than water or heptane were utilized as anti-solvents, the vast majority of the experiments generated no solids. A few others generated material, but the quantity was too small to characterize.
Ambient temperature (RT) solvent/anti-solvent precipitation experiments were generally unsuccessful. A set of experiments utilizing tetrahydrofuran as the solvent and either water or heptane as the anti-solvent generated enough solids for characterization. When hexafluoroisopropyl alcohol (HFIPA) was used as a solvent, the solution discolored (yellow/brown/red). Either Form 1 or disordered Compound 2 was generated from these experiments. The vast majority of the other solvent combinations attempted produced solids free solutions. However, sonicating these solutions generated a number of solid materials. All the recovered solids from these sonication experiments were Compound 2 Form 1.
Evaporative and slow cool experiments that generated materials were almost always Compound 2 Form 1. The only exception was two evaporative experiments (from tetrahydrofuran and dichloromethane) that generated glasses. Upon characterization, these proved to be highly disordered.
The disordered Compound 2 was subjected to water activity slurries in methanol at ambient temperature and Form 1 resulted.
The procedures for the conditions in Table 7 are discussed below.
An enabling form study was carried out at ambient, elevated (approximately 60° C.) and sub-ambient (2-8° C.) temperature (Table 8). All generated materials were Compound 2 Form 1.
The characteristics of Compound 2 Form I Polymorph are shown in Table 9. The XRPD pattern indicated that the material was crystalline. The pattern was successfully indexed (
XRPD patterns were collected with a PANalytical X'Pert PRO MPD diffractometer using an incident beam of Cu radiation produced using an Optix long, fine-focus source. An elliptically graded multilayer mirror was used to focus Cu Kα X-rays through the specimen and onto the detector. Prior to the analysis, a silicon specimen (NIST SRM 640e) was analyzed to verify the observed position of the Si 111 peak is consistent with the NIST-certified position. A specimen of the sample was sandwiched between 3-μm-thick films and analyzed in transmission geometry. A beam-stop, short antiscatter extension, and antiscatter knife edge were used to minimize the background generated by air. Soller slits for the incident and diffracted beams were used to minimize broadening from axial divergence. Diffraction patterns were collected using a scanning position-sensitive detector (X'Celerator) located 240 mm from the specimen and Data Collector software v. 2.2b. The data acquisition parameters for each pattern are displayed above the image in the Data section of this report.
DSC (Differential Scanning calorimetry) was performed using a TA Instruments Q2000 differential scanning calorimeter. Temperature calibration was performed using NIST-traceable indium metal. The sample was placed into an aluminum DSC pan, covered with a lid, and the weight was accurately recorded. A weighed aluminum pan configured as the sample pan was placed on the reference side of the cell. The data acquisition parameters and pan configuration for each thermogram are displayed in the image in the Data section of this report. The method code on the thermogram is an abbreviation for the start and end temperature as well as the heating rate; e.g., −30-250-10 means “from −30° C. to 250° C., at 10° C./min”. The following table summarizes the abbreviations used in each image for pan configurations:
Modulated Differential Scanning calorimetry (mDSC) data were obtained on a TA Instruments Q2000 differential scanning calorimeter equipped with a refrigerated cooling system (RCS). Temperature calibration was performed using NIST-traceable indium metal. The sample was placed into an aluminum DSC pan, and the weight was accurately recorded. The pan was covered with a lid perforated with a laser pinhole, and the lid was crimped. A weighed, crimped aluminum pan was placed on the reference side of the cell. Data were obtained using a modulation amplitude of ±0.8° C. and a 60 second period with an underlying heating rate of 2° C./minute from 30 to 250° C. The reported glass transition temperatures are obtained from the inflection point of the step change in the reversing heat flow versus temperature curve.
Thermogravimetric (TG) TG analyses were performed using a TA Instruments Q5000 IR thermogravimetric analyzer. Temperature calibration was performed using nickel and Alumel™. Each sample was placed in an aluminum pan. The sample was hermetically sealed, the lid pierced, then inserted into the TG furnace. The furnace was heated under nitrogen. The data acquisition parameters for each thermogram are displayed in the image in the Data section of this report. The method code on the thermogram is an abbreviation for the start and end temperature as well as the heating rate; e.g., 25-350-10 means “from 25° C. to 350° C., at 10° C./min”.
Hot stage microscopy was performed using a Linkam hot stage (FTIR 600) mounted on a Leica DM LP microscope equipped with a SPOT Insight™ color digital camera. Temperature calibrations were performed using USP melting point standards. Samples were placed on a cover glass, and a second cover glass was placed on top of the sample. As the stage was heated, each sample was visually observed using crossed polarizers and a first order red compensator. Images were captured using SPOT software (v. 4.5.9).
