Definitions
- the present disclosure generally relates to novel crystalline Forms of heteroaryl compounds, compositions comprising the same, methods of preparing and methods of using the same, e.g., for inhibiting a kinase and/or for treating various diseases or disorders, such as autoimmune diseases described herein.
- the Janus kinase (JAK) family is a small family of receptor-associated tyrosine kinases that are essential for the signal cascade downstream of type I and type II cytokine receptors.
- Type I and type II cytokine receptors which compose a family of receptors bound by over 50 cytokines, interleukins, interferons (IFNs), colony-stimulating factors (CSFs) and hormones—share a distinct intracellular signaling pathway mediated by JAKs that bind directly to the intracellular domains of type I and type II cytokine receptors and not to other classes of cytokine receptor.
- JAK-dependent cytokines are major contributors to immunopathology.
- type I and type II cytokines The dependence of type I and type II cytokines on JAKs was established in a variety of genetic models from mutagenized cell lines and knockout mice to humans. Polymorphisms in JAK and signal transducer and activator of transcription (STAT) genes are associated with autoimmunity, and loss of function mutations cause immunodeficiency due to the inability of type I and type II cytokines to transmit signals through their receptors. The critical role of JAKs in type I and type II cytokine signaling strongly argues that interfering with the activity of these kinases could lead to a new class of immunomodulatory drugs.
- STAT signal transducer and activator of transcription

The reaction mixture was then cooled to RT, quenched with water and filtered. The filter cake was rinsed with water and collected. At a temperature of 65° C., the crude product was slurried with a mixed solvent of tetrahydrofuran and isopropanol (V/V, 1/1) to give Compound 1-2 (a white solid, 251 g with a yield of 91%). LCMS: 478.1 [M+1] + .
- Step 2 Under nitrogen, Compound 1-2 (200 g) and N, N-diisopropylethylamine (81 g) were added to tetrahydrofuran (1200 mL), and heated to 65° C. A solution of cyclopropanecarbonyl chloride (52.6 g) in THF (500 mL) was added dropwise to react for 2 hours. The reaction mixture was cooled to 25° C., quenched with water, and extracted with dichloromethane. The organic phase is washed with water, concentrated under reduced pressure, and slurried by adding isopropanol at 80° C. for 1 hour to give Compound 1-3 (a pale yellow solid, 196 g with a yield of 87%).
- Step 3 Under nitrogen, Compound 1-3 (160 g) was added to 1,4-dioxane (1600 mL). At a temperature below 30° C., a solution of potassium peroxomonosulfate (325 g) in water (700 mL) was added to react at 30° C. for 24 hours. The reaction mixture was filtered and washed with dichloromethane. The filtrate was washed with 5% sodium sulfite aqueous solution and water, respectively. After the organic phase is concentrated, methanol is added to slurry at 65° C. for 1 hour to give Compound 1-4 (a white solid, 121 g with a yield of 72%).

Abstract
Provided herein are compounds, crystalline free forms, crystalline salt forms, and pharmaceutical compositions of Compound 1. Also provided are methods of preparing and methods of using the same, e.g., for inhibiting a kinase and/or for treating various diseases or disorders, such as autoimmune diseases.
Description
- This application claims priority of Chinese Application No. CN202210700943.X, filed on Jun. 20, 2022, the content of which is incorporated herein by reference in its entirety.
- In various embodiments, the present disclosure generally relates to novel crystalline Forms of heteroaryl compounds, compositions comprising the same, methods of preparing and methods of using the same, e.g., for inhibiting a kinase and/or for treating various diseases or disorders, such as autoimmune diseases described herein.
- The Janus kinase (JAK) family is a small family of receptor-associated tyrosine kinases that are essential for the signal cascade downstream of type I and type II cytokine receptors. Type I and type II cytokine receptors—which compose a family of receptors bound by over 50 cytokines, interleukins, interferons (IFNs), colony-stimulating factors (CSFs) and hormones—share a distinct intracellular signaling pathway mediated by JAKs that bind directly to the intracellular domains of type I and type II cytokine receptors and not to other classes of cytokine receptor. JAK-dependent cytokines are major contributors to immunopathology. The dependence of type I and type II cytokines on JAKs was established in a variety of genetic models from mutagenized cell lines and knockout mice to humans. Polymorphisms in JAK and signal transducer and activator of transcription (STAT) genes are associated with autoimmunity, and loss of function mutations cause immunodeficiency due to the inability of type I and type II cytokines to transmit signals through their receptors. The critical role of JAKs in type I and type II cytokine signaling strongly argues that interfering with the activity of these kinases could lead to a new class of immunomodulatory drugs.
- A new compound and its novel crystalline forms and salts that modulate cytokines and/or interferons, such as IL-12, IL-23 and/or IFNα, should deliver a pharmacological response that favorably treats one or more of the conditions described herein and may provide substantial therapeutic benefits to a wide variety of patients in need thereof.

Step 1 can be carried out by using cesium fluoride in N-methylpyrrolidone. In some embodiments,Step 2 can be carried out at a temperature of 50-80° C., preferably 60-70° C., and more preferably at 65° C. In some embodiments,Step 3 can be performed by using potassium peroxomonosulfate as an oxidizing agent. In some embodiments,Step 4 can be performed by using an acid, such as trifluoroacetic acid. - In some embodiments,
Compound 1 can be in a solid form, such as an amorphous form, a crystalline form, or a combination thereof. In some embodiments,Compound 1 can be an amorphous form. In some embodiments,Compound 1 can be in a crystalline form (e.g., in any one or more crystalline forms I, II, III, IV, V, VI, VII, VIII, IX, X, XI, XII, XIII, XIV, XV, XVI, or XVII as described herein). As used herein, whenCompound 1 is said to exist or be in one particular solid form (e.g., a crystalline form), it should be understood that in some embodiments, the compound can exist predominantly in that particular form. However, in some embodiments, the compound can also exist in the particular form, in a mixture with one or more other solid forms, including amorphous form. For example, whenCompound 1 is said to exist or be in Form III,Compound 1 can exist predominantly in Form III, such as more than 80% by weight, more than 90% by weight, or more than 95% by weight ofCompound 1 are in Form III, or no other solid form can be identified, for example, by XRPD; or in some embodiments,Compound 1 can exist in Form III, in a mixture with one or more solid forms such as an amorphous form. -
Compound 1 herein is typically in a substantially pure form. For example, in some embodiments,Compound 1 can have a purity of greater than 70%, preferably greater than 90% (e.g., greater than 95%, greater than 97%, greater than 98%, greater than 98.5%), by weight, by HPLC area, or both. In some embodiments, theCompound 1 can be characterized by a purity by weight and/or by HPLC area of about 70%, about 75%, about 80%, about 85%, about 90%, about 95%, about 97%, about 99%, or any ranges between the specified values. For example, in some embodiments, theCompound 1 can be characterized by a purity by HPLC area of about 70%, about 75%, about 80%, about 85%, about 90%, about 95%, about 97%, about 99%, or any ranges between the specified values. The substantiallypure Compound 1 can be in a solid form (e.g., a crystalline pure or salt form described herein, amorphous form, or a combination thereof) or in a solution, suspension, or another form. In some embodiments, the substantiallypure Compound 1 can be in crystalline Form III. For the avoidance of doubt, a composition comprising the substantiallypure Compound 1 herein and one or more other ingredients should be understood as a mixture of the substantiallypure Compound 1 herein and the one or more other ingredients, for example, such composition can be obtained directly or indirectly from mixing the substantiallypure Compound 1 with the one or more other ingredients, such as solvent, pharmaceutically acceptable excipients, etc. - In some embodiments, the

To be clear, when it is said that the XRPD pattern of Form I has the characteristic peaks ofFIG. 1 a or Table 1 or is substantially the same asFIG. 1 a , it does not require that the XRPD pattern have the same relative intensities for the corresponding peaks as shown inFIG. 1 a or Table 1, as applicable. It suffices that the XRPD pattern includes the peaks at the respective diffraction angels (2 theta, ±0.2°) corresponding to the peaks as shown inFIG. 1 a or Table 1, as applicable, regardless of their relative intensities.
