SYNTHESIS OF BRUTON’S TYROSINE KINASE INHIBITORS CLAIM OF PRIORITY [0001] This application claims priority to Greek Application No. GR20220100151 filed on February 18, 2022, European Application No. EP 22167032.6 filed on April 6, 2022, and European Application No. EP22178413.5 filed on June 10, 2022, each of which is incorporated by reference in its entiriety. TECHNICAL FIELD [0002] The present disclosure is directed to the synthesis of small molecule tyrosine kinase inhibitors. BACKGROUND [0003] Human Bruton’s tyrosine kinase (“BTK”) is a ~76 kDa protein belonging to the Tec family of non-receptor tyrosine kinases. Tec kinases form the second largest family of cytoplasmic tyrosine kinases in mammalian cells, which consists of four other members in addition to BTK: the eponymous kinase TEC, ITK, TXK/RLK and BMX. Tec kinases are evolutionarily conserved throughout vertebrates. They are related to, but structurally distinct from, the larger Src and Syk kinase families. Tec family proteins are abundantly expressed in hematopoietic tissues and play important roles in the growth and differentiation of blood and endothelial cells in mammals. Based upon BTK expression from IHC studies described in the art, Btk inhibition has the potential to modulate biology associated with B cells, macrophages, mast cells, osteoclasts, and platelet microparticles.

DETAILED DESCRIPTION [0017] The disclosure may be more fully appreciated by reference to the following description, including the following glossary of terms and the concluding examples. It is to be appreciated that certain features of the disclosed compositions and methods which are, for clarity, described herein in the context of separate aspects, may also be provided in combination in a single aspect. Conversely, various features of the disclosed compositions and methods that are, for brevity, described in the context of a single aspect, may also be provided separately or in any subcombination. It will be understood by those within the art that, in general, terms used herein, and especially in the appended claims (for example, bodies of the appended claims) are generally intended as “open” terms (for example, the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases "at least one" and "one or more" to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles "a" or "an" limits any particular claim containing such introduced claim recitation to aspects containing only one such recitation, even when the same claim includes the introductory phrases "one or more" or "at least one" and indefinite articles such as "a" or "an" (for example, “a” and/or “an” should be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should be interpreted to mean at least the recited number (for example, the bare recitation of "two recitations," without other modifiers, means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (for example, “ a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances where a convention analogous to “at least one of A, B, or C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (for example, “ a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase “A or B” will be understood to include the possibilities of “A” or “B” or “A and B.” [0018] In addition, where features or aspects of the disclosure are described in terms of Markush groups, those skilled in the art will recognize that the disclosure is also thereby described in terms of any individual member or subgroup of members of the Markush group.

The heterocycloalkyl group may be attached at any heteroatom or carbon atom of the ring such that the result is a stable structure. Examples of suitable heterocycloalkyl groups include, but are not limited to, azepanyl, aziridinyl, azetidinyl, pyrrolidinyl, dioxolanyl, imidazolidinyl, pyrazolidinyl, piperazinyl, piperidinyl, dioxanyl, morpholinyl, dithianyl, thiomorpholinyl, oxazepanyl, oxiranyl, oxetanyl, quinuclidinyl, tetrahyofuranyl, tetrahydropyranyl, piperazinyl, hexahydro-5H-[1,4]dioxino[2,3-c]pyrrolyl, benzo[d][1,3]dioxolyl, and the like.

[0034] “Compounds of the present disclosure,” and equivalent expressions, are meant to embrace compounds of the Formula (I), compounds of the Formula (II), compounds of the Formula P-(II), and compounds of the Formula M-(II), as described herein, which expression includes the pharmaceutically acceptable salts, and the solvates, e.g., hydrates, dihydrates, and polymorphs thereof, where the context so permits. Compounds of the present disclosure also include the stereoisomers (including but not limited to enantiomers and diastereomers) thereof and the tautomeric forms thereof. Similarly, reference to intermediates, whether or not they themselves are claimed, is meant to embrace their salts, and solvates, where the context so permits. [0035] Suitable pharmaceutically acceptable salts of the compounds of disclosure include acid addition salts that can, for example, be formed by mixing a solution of the compound with a solution of a pharmaceutically acceptable acid such as, hydrochloric acid, sulfuric acid, fumaric acid, maleic acid, succinic acid, acetic acid, benzoic acid, citric acid, tartaric acid, carbonic acid or phosphoric acid. Furthermore, where compounds of the disclosure carry an acidic moiety, suitable pharmaceutically acceptable salts thereof may include alkali metal salts such as, sodium or potassium salts; alkaline earth metal salts such as, calcium or magnesium salts; and salts formed with suitable organic ligands such as, quaternary ammonium salts. Thus, representative pharmaceutically acceptable salts include acetate, benzenesulfonate, benzoate, bicarbonate, bisulfate, bitartrate, borate, bromide, calcium edetate, camsylate, carbonate, chloride, clavulanate, citrate, dihydrochloride, edetate, edisylate, estolate, esylate, fumarate, gluceptate, gluconate, glutamate, glycollylarsanilate, hexylresorcinate, hydrabamine, hydrobromide, hydrochloride, hydroxynaphthoate, iodide, isothionate, lactate, lactobionate, laurate, malate, maleate, mandelate, mesylate, methylbromide, methylnitrate, methylsulfate, mucate, napsylate, nitrate, N-methylglucamine ammonium salt, oleate, pamoate (embonate), palmitate, pantothenate, phosphate/diphosphate, polygalacturonate, salicylate, stearate, sulfate, subacetate, succinate, tannate, tartrate, teoclate, tosylate, triethiodide, and valerate. [0036] As used herein, “solvate” may be a solvate with water (i.e., a hydrate, a dihydrate) or with an organic solvent. [0037] For the purposes of this disclosure, the terms "crystalline form" and "polymorph" are synonymous. Characterizing information for crystalline forms is provided herein. It should be understood that the determination of a particular form can be achieved using any portion of the characterizing information that one skilled in the art would recognize as sufficient for establishing the presence of a particular form. For example, even a single distinguishing peak can be sufficient for one skilled in the art to appreciate that a particular form is present. [0038] As used herein, the term “isotopic variant” refers to a compound that contains unnatural proportions of isotopes at one or more of the atoms that constitute such compound. For example, an “isotopic variant” of a compound can be radiolabeled, that is, contain one or more non-radioactive isotopes, such as for example, deuterium ( ² H or D), carbon-13 ( ¹³ C), nitrogen-15 ( ¹⁵ N), or the like. It will be understood that, in a compound where such isotopic substitution is made, the following atoms, where present, may vary, so that for example, any hydrogen may be ² H/D, any carbon may be ¹³ C, or any nitrogen may be ¹⁵ N, and that the presence and placement of such atoms may be determined within the skill of the art. Likewise, the disclosure may include the preparation of isotopic variants with radioisotopes, in the instance for example, where the resulting compounds may be used for drug and/or substrate tissue distribution studies. Radiolabeled compounds of the disclosure can be used in diagnostic methods such as Single- photon emission computed tomography (SPECT). The radioactive isotopes tritium, i.e. ³ H, and carbon-14, i.e. ¹⁴ C, are particularly useful for their ease of incorporation and ready means of detection. Further, compounds may be prepared that are substituted with positron emitting isotopes, such as ¹¹ C, ¹⁸ F, ¹⁵ O and ¹³ N, and would be useful in Positron Emission Topography (PET) studies for examining substrate receptor occupancy. [0039] All isotopic variants of the compounds of the disclosure, radioactive or not, are intended to be encompassed within the scope of the disclosure. [0040] It is also to be understood that compounds that have the same molecular formula but differ in the nature or sequence of bonding of their atoms or the arrangement of their atoms in space are termed “isomers.” Isomers that differ in the arrangement of their atoms in space are termed “stereoisomers,” for example, diastereomers, enantiomers, and atropisomers. [0041] Stereoisomers that are not mirror images of one another are termed “diastereomers” and those that are non-superimposable mirror images of each other are termed “enantiomers.” When a compound has an asymmetric center, for example, it is bonded to four different groups, a pair of enantiomers is possible. An enantiomer can be characterized by the absolute configuration of its asymmetric center and is described by the R-and S-sequencing rules of Cahn and Prelog, or by the manner in which the molecule rotates the plane of polarized light and designated as dextrorotatory or levorotatory (i.e., as (+) or (-)-isomers respectively). A chiral compound can exist as either individual enantiomer or as a mixture thereof. A mixture containing equal proportions of the enantiomers is called a “racemic mixture.” [0042] “Atropisomers” refer to stereoisomers that arise because of hindered rotation around a single bond. Atropisomers are named as either M or P throughout. [0043] “Tautomers” refer to compounds that are interchangeable forms of a particular compound structure, and that vary in the displacement of hydrogen atoms and electrons. Thus, two structures may be in equilibrium through the movement of π electrons and an atom (usually H). For example, enols and ketones are tautomers because they are rapidly interconverted by treatment with either acid or base. Another example of tautomerism is the aci-and nitro-forms of phenyl nitromethane, that are likewise formed by treatment with acid or base. [0044] Tautomeric forms may be relevant to the attainment of the optimal chemical reactivity and biological activity of a compound of interest. [0045] The compounds of this disclosure may possess one or more asymmetric centers; such compounds can therefore be produced as individual (R)-or (S)-stereoisomers or as mixtures thereof. [0046] Unless indicated otherwise, the description or naming of a particular compound in the specification and claims is intended to include both individual enantiomers and mixtures, racemic or otherwise, thereof. Within the present disclosure, any open valency appearing on a carbon, oxygen, or nitrogen atom in any structure described herein indicates the presence of a hydrogen atom. Where a chiral center exists in a structure, but no specific stereochemistry is shown for that center, both enantiomers, separately or as a mixture, are encompassed by that structure. The methods for the determination of stereochemistry and the separation of stereoisomers are well-known in the art.

Example 19: Crystallization-Induced Diastereomer Transformation (CIDT) of Formula (II) [00141] Crystallization-Induced Diastereomer Transformation (CIDT) for a compound of Formula (II). The CIDT process is used to convert a mixture of P, M atropisomers (of any diastereomeric ratio, d.r.100:0 to 0:100) of Formula (II) into the desired P-isomer, which is isolated as a dihydrate solid in the same process. [00142] The CIDT process developed works by preferentially removing the P isomer out of a solution containing 1/1 P/M isomer ratio by crystallization, which in turn creates an enrichment in favour of the M isomer in the solution. Subsequently, an epimerization reaction converts the M isomer into the P isomer, which crystallizes further in the reactor. The process continues until most/all of the M isomer is converted to the P isomer. The preferential crystallization can take place in the same reactor as the epimerization, or most efficiently, the two processes can be spatially decoupled (by coupled stirred tanks or by stirred tanks coupled with tubular reactors in loop configuration), as shown in Figure 1. Solubility and epimierization [00143] A broad solvent screen was performed in standard organic solvents (both water-miscible and immiscible solvents) to determine the epimerization kinetics and the main results are presented in Table 1 which shows rotational energy barrier, ∆ ^^ (kJ/mol) for epimerization of Formula (II), and half lives, ^^ t 20 °C, 85 °C, 100 °C and 120 °C in various solvents and their water mixtures.

[00144] In parallel, an extensive solvent screen for solubility and form of P and M isomers showed that an important difference of solubility between P and M form exists in many solvent systems (Table 2, which shows the solubilities of P and M forms of Formula (II) at 10 °C, 25 °C and 50 °C in various solvent systems and their water mixtures). In several solvent compositions (for example 1-propanol/water), the solubility difference is more than 10 fold. Moreover, this solubility difference can be tuned by changing the ratio between 1- propanol/water. Therefore, M form can be efficiently converted even starting from a 1:1 d.r. mixture. Table 2 * form change was observed after 24h equilibration. CIDT protocol in 1-propanol/water solvent mixture Phase 1: Crude dissolution and epimerization [00145] During this phase, the crude P/M isomer mixture (of any d.r.) is dissolved in 1- propanol to give a homogeneous solution. Subsequently, the mixture is heated to an appropriate temperature and held for an appropriate amount of time to allow complete epimerization (P/M ratio of 1/1). Detailed process steps: 1) Charge 1 kg crude P or M isomer or mixture (purity crude used ≈ 92.2 wt% adjust values accordingly if different crude quality is used) 2) Add 2.49 L/kg 1-propanol 3) Start stirring at 300 rpm 4) Heat to 95 °C (all solids dissolve before reaching 95 °C) 5) Wait 10 h to fully epimerize 6) Cool to 25 °C Sample liq. to confirm complete epimerization ^ LC for diastereomeric ratio. [00146] In case crude solution is used, perform solvent switch to 1-propanol. If crude is already a P/M mixture of 1/1 ratio, holding time of 10 h is not needed. Hence, holding time can be adapted to ensure complete dissolution (homogeneous mixture). Phase 2: Seeded preferential crystallization of P-isomer [00147] During this phase, supersaturation is generated in the P/M isomer mixture (1/1 ratio) by addition of water and seeds of the P-isomer are introduced to start preferential crystallization of that isomer. However, even in the absence of seeds, P-isomer will preferentially crystallize, and M will stay in solution. Detailed process steps: 1) Add 0.5 L/kg water 2) Seed with 0.01 kg/kg pure P-isomer (dihydrate) 3) Wait 5 h (seed ageing) 4) Add 1.5 L/kg water in 3h 5) Cool to 10 °C at 0.2 °C/min 6) Wait overnight to fully desaturate Sample liq. to confirm preferential P-isomer crystallization → LC for P and M concentration. Phase 3: Coupled crystallization/epimerization in flow reactor [00148] During this phase, the enriched mother liquor in the M-isomer is continuously filtered from the suspension and pumped into a tubular reactor held at a higher temperature to allow conversion to the desired P-isomer. The converted mother liquor is then returned to the crystallizer to allow additional P isomer crystallization. Detailed process steps: 1) Start mother liquor re-circulation through heated tubular loop reactor Parameters: a. In-line filter (KIMBLE 2 um Ultra-Ware SS Inlet filter) b.

Phase 4: Product isolation [00149] During this phase, product is isolated from the suspension by filtration, washing is performed, followed by humidified drying. Detailed process steps: 1) Filter out the solids 2) Wash solids twice each time with 0.7 L/kg of 1-propanol/water 30/70 w/w% 3) Dry solids in vacuum at 40 °C under humidified conditions for 24 h Crystal Yield 86 % / purity ≈ (99/1 P/M).

CIDT protocol in propylene carbonate/water solvent mixture Phase 1: Crude dissolution and epimerization [00151] During this phase, the crude P/M isomer mixture (of any d.r.) is dissolved in propylene carbonate to give a homogeneous solution. Subsequently, the mixture is heated to an appropriate temperature and held for an appropriate amount of time to allow complete epimerization (P/M ratio of 1/1). Detailed process steps: 1) Charge 1 kg crude P or M isomer or mixture (purity crude used ≈ 92.2 wt% adjust values accordingly if different crude quality is used) 2) Add 4.7 L/kg propylene carbonate 3) Start stirring at 350 rpm (on EMAX 102, adjust accordingly per setup/scale) 4) Heat to 100 °C (all solids dissolve before reaching 100 °C) 5) Wait 6 h to fully epimerize 6) Cool to 80 °C Sample liq. to confirm complete epimerization ^ LC for diastereomeric ratio. Phase 2: Preferential crystallization of P-isomer [00152] During this phase, supersaturation is generated in the P/M isomer mixture (1/1 ratio) by addition of water and P-isomer preferential crystallization occurs. Detailed process steps: 1) Add 0.42 L/kg water 2) Cool to 25 °C over 4h 3) Wait 5 h Sample liq. to confirm preferential P-isomer crystallization ^ LC for P and M concentration. Phase 3: Coupled crystallization/epimerization in flow reactor [00153] During this phase, the enriched mother liquor in the M-isomer is continuously filtered from the suspension and pumped into a tubular reactor held at a higher temperature to allow conversion to the desired P-isomer. The converted mother liquor is then returned to the crystallizer to allow additional P isomer crystallization.

Phase 4: Product Isolation [00154] During this phase, product is isolated from the suspension by filtration, washing is performed, followed by humidified drying. Detailed process steps: 1) Filter out the solids 2) Wash solids twice each time with 0.75 L/kg of propylene carbonate/water 93/7 w/w% 3) Dry solids in vacuum at 45 °C under humidified conditions for 24 h Crystal yield ≈ 83 % / purity ≈ (99/1 P/M). [00155] Figure 3 shows typical evolution of P and M isomer concentrations in the liquid during re-circulation in the loop reactor in propylene carbonate/water system. Batch CIDT protocol [00156] In a flask, 5.0 g of 1:1 ratio P/M was added to a mixture of IPA/water 2/1 (25 mL). The mixture was heated to 80 ℃ for 1 hour then cooled down to 50 ℃. The mixture was stirred at 50 ℃ for 54 hours. The suspension was then cooled down to 10 ℃. The in-situ yield was 60 % of P (and 40 % of M). The suspension was filtered to yield P as a white solid (2.7 g, 88.9% assay, 48 % yield). Example 20: NMR of N-((1R,2S)-2-acrylamidocyclopentyl)-5-(6-isobutyl-4-methylpy ridin-3-yl)- 4-oxo-4,5-dihydro-3H-1-thia-3,5,8-triazaacenaphthylene-2-car boxamide dihydrate (Formula P- (II)) [00157] The following is a NMR spectra of material produced in Example 11. ¹ H NMR (400 MHz, DMSO-D ₆ ): δ 10.1 (s, 1H), 8.46 (s, 1H), 8.33 (d, J = 5.6 Hz, 1H), 7.88 (d, J = 7.6 Hz, 1H), 7.77 (d, J = 7.6 Hz, 1H), 7.36 (s, 1H), 6.22 (dd, J = 6.8, 16.8 Hz, 1H), 6.11 (dd, J = 2.4, 17.2 Hz, 1H), 5.94 (d, J = 5.6 Hz, 1H), 5.57 (dd, J = 2, 10 Hz, 1H), 4.32 (m, 2H), 2.65 (d, J = 6.8 Hz, 2H), 2.13 (m, 4H), 2.10-1.4 (m, 6H), 0.93 (d, J = 6.8 Hz, 1H). Example 21: SAR studies [00158] Initial structure-activity relationships for a new series of BTK inhibitors exemplified by Compound A (Table 3) have been previously conducted, (Tichenor, et al., ACS Med. Chem. Lett.2021, 12, 782-790) with an acrylamide electrophile designed to engage in a covalent bond with Cys481. Despite the potent covalent inhibition potency in vitro and in vivo, the developability of Compound A was limited by the low aqueous solubility and low oral bioavailability (<1%) when dosed as a crystalline suspension, precluding its development as a therapeutic agent. Therefore, subsequent optimization of Compound A focused on increasing aqueous solubility and oral bioavailability from solid formulations suitable for preclinical tolerability assessment and advancement into human clinical trials. The development of the structure-activity relationship was conducted by characterizing the non-covalent affinity of each inhibitor for BTK (KI) and the first order rate constant for irreversible covalent bond formation (k _inact ). The second order rate constant k _inact /K _I ratio is used to assess the covalent inhibitor potency because it is independent of incubation time and substrate concentrations (Copeland, R. A. Evaluation of Enzyme Inhibitors in Drug Discovery : a Guide for Medicinal Chemists and Pharmacologists; 2nd ed.; Wiley: Hoboken, N.J., 2013). Table 3 [00159] An initial set of analogs was designed to reduce lipophilicity by conducting a nitrogen scan on the proximal phenyl right (Table 4) while maintaining the tricyclic core and acrylamide. Compared to the highly potent phenyl derivative 2 (kinact/KI = 13,832 s ⁻¹ ), pyridyl isomers C and D imparted moderately increased aqueous solubility but a 20-fold loss in BTK potency. Incorporation of a methyl group ortho to the core heterocycle (5-10) restricts rotation around the N-aryl bond, yielding a pair of stable atropisomers (Tichenor, et al., ACS Med. Chem. Lett.2021, 12, 782-790). Incorporation of an ortho-methyl into examples C and D increased BTK potency by improving the BTK k _inact /K _I ratio up to 16-fold (Compound F) by increasing the reversible binding affinity KI (0.0276 ^M) while the first order rate constant for covalent bond formation k _inact (0.000352±6e ⁻⁰⁵ s ^-1 ) remained unchanged across the series. The 4-methyl pyridyl Compound F maintained BTK potency that was comparable to Compound A with reduced cLogP, albeit with persistent low aqueous solubility and metabolic instability. Table 4: Introduction of Back-Pocket Modifications to Increase Aqueous Solubility

[00160] Subsequent analogs focused on replacing the distal aromatic ring with lower molecular weight aliphatic substituents to reduce lipophilicity and increase the fraction of sp ³ hybridized carbon atoms (Compound B, Fsp ³ = 13%). The cyclopentyloxy substituent in Compound G displayed equivalent potency compared to the phenoxy derivative F, but as the alkoxy substituent was further truncated with iteratively smaller alkoxy groups (examples H–J) with a corresponding reduction in cLogP, the corresponding BTK kinact/KI values declined up to 8-fold for Compound I (1663 M ⁻¹ s ⁻¹ ) compared to Compound B with a concomitant improvement in microsomal stability and pH 2 and 7 aqueous solubility. Replacing the oxygen connection with a carbon as in isobutyl derivative J further improved pH 2 and 7 aqueous solubility (350/23 ^M), with a moderate improvement in potency relative to Compound I. The improved profile of Compound I corresponded to increasing Fsp ³ (32%) and reducing cLogP (3.6) relative to Compound B. Consistent with the SAR trends in Table 4, the non-covalent binding affinity component K _I had the largest impact on differences in inhibitor potency, while the kinact values varied by less than 2-fold across a structurally diverse set of examples . [00161] Further optimization of J was approached with the goal of identifying the optimal linker length to position the acrylamide to bind and engage Cys481 in covalent bond formation (Table 5). The BTK KI proved to be sensitive to the length and orientation of the linker. Replacing the amino-piperidine in J with an amino-pyrrolidine (K) or an ethylene diamine (L) caused a reduction in potency by approximately 20-fold by reducing K _I to micromolar levels (2.55, 2.43, respectively). However, the improved microsomal stability of K and L relative to J justified additional linker exploration. The linker based on cis-cyclopentyl diamine (M) imparted considerably improved potency compared to other linkers (10, 11, 12) and increased microsomal stability compared to the piperidine derivative J (38 min vs 6 min). Compound M also maintained high pH 2 solubility, and measurable pH 7 solubility, making it an attractive candidate for in vivo profiling. Table 5: Optimization of Diamine Acrylamide Linkers H li [00162] Relative to the series benchmark Compound A, Compound M is characterized by reduced lipophilicity and increased Fsp ³ (32%), corresponding to increased pH 2 and 7 aqueous solubility while maintaining equivalent potency at suppressing anti-IgM induced B cell activation in human whole blood (Table 6). The activity of Compound M was assessed in rat and human whole blood assays using anti-IgD and anti-IgM stimulation, respectively, to trigger B- cell activation via B-cell receptor. While Compound M displays reduced potency in the mouse CD69 splenocyte assay, Compound M is 3-fold more potent in rat whole blood and equipotent in human whole blood potency compared to Compound A. The potent rat whole blood activity of Compound M may be attributed to the 6 to 10-fold increase in free fraction. Table 6. Profile of Compound M (compound of Formula II) Example 22: XRPD Analysis of Crystalline Form B of Formula P-(II) dihydrate [00163] X-ray powder diffraction (XRPD) test was carried out on a Bruker D8 Advance X-ray powder diffractometer.

Tested by Tzero hermetically sealed pan: [00168] Differential scanning calorimetry was carried out on a TA Instruments discovery DSC-2500 differential scanning calorimeter equipped with a RCS cooling unit. Transfer ~1.6 mg of the compound into a Tzero aluminum sample pan from TA instruments. Close the sample pan with the Tzero lid (hermetically sealed) and record the DSC curve. DSC testing with Tzero hermetically sealed pan parameters are shown in Table11. Table 11.

The second endotherm cannot be assigned to a specific form under the specific measurement conditions.

About 8.7 mg of the compound was transferred into a standard aluminum sample pan from TA instruments after it was tared and record the TGA curve. TGA testing parameters are shown in Table12. Table 12.

Example 26: Rotational barrier of compound of Formula (II) [00172] The rotational energy barrier of compound of Formula (II) atropisomers was estimated according to the method known in the art. The rotational barrier was determined in several solvents and their aqueous mixtures and the results are reported in Table 13, where an average value of 120.5 kJ mol ^-1 or 28.8 kcal mol ^-1 , corresponding to epimerization half-lives of 63.8 and 4.0 months at 20 °C and 37 °C, respectively, were obtained, placing this compound on the top segment of Class 2 atropisomers according to the classification systems known in the art. The rotational barrier is slightly influenced by the solvent and increases in the order 1-butanol < 2-butanol < 1-propanol < propylene carbonate. Additionally, increasing amounts of water increased substantially the rotational barrier in all solvents with the highest value obtained in 1- propanol/water 33/67 w/w% system. Unfortunately, due to the low aqueous solubility of compound of Formula (II) in water, epimerization studies could not be accurately conducted in pure water. Table 13: Experimentally determined (80-100 °C) rotational energy barriers, ∆ ^^ _^ , and epimerization half-lives, for compound of Formula (II) in alcohols, propylene carbonate and various aqueous mixtures thereof. [00173] Enriched compound of Formula (II) of the P isomer was dissolved in the respective solvent to create a concentration of ~ 1 wt% and was placed in a standard screw cap vial (1.8 mb) equipped with a magnetic stirring bar. Subsequently, the vial was placed in the heating block of a parallel reactor setup (Crystallb, Technobis B.V.) which was preheated to the desired temperature (80 °C - 100 °C, depending on the solvent). At given time intervals, small aliquot samples were taken in an HPLC vial, diluted, and the diastereomeric excess of the mixture was determined by an UPLC apparatus, equipped with an Acquity UPLC BEH Cl 8 column (0.6 ml/min, gradient lOmM ammonium acetate acetonitrile 95-5 v/v % and acetonitrile at 35 °C). The time points and corresponding decay of diastereomeric excess (d.e.) were plotted as t vs In (1/d. e. ) to determine the interconversion rate constant, rotational energy barrier and epimerization half-life at the respective solvent and temperature: where [P], [M] are the concentrations of the P and M isomers, respectively, k _e is the interconversion rate constant (s ^-1 ), is the rotational energy barrier (kJ mol ^-1 ), T is the absolute temperature, k _B , h. and R are the Boltzmann, Planck and universal gas constants, respectively and t _1/2 is the epimerization half-life.
