Claims (21)

1 - 8 . (canceled)

9 . A process of preparing crystalline Form A of Compound (I):

wherein C* is a stereochemical center, and

wherein crystalline Form A is characterized by an X-ray powder diffractogram having a signal at at least three two-theta values chosen from 5.6±0.2, 12.7±0.2, 16.5±0.2, 17.0±0.2, 17.7±0.2, 18.7±0.2, 19.2±0.2, 20.7±0.2, 22.2±0.2, and 24.4±0.2,

the process comprising:

adding isopropyl acetate to amorphous (R)-2-[3-[4-amino-3-(2-fluoro-4-phenoxy-phenyl)pyrazolo[3,4-d]pyrimidin-1-yl]piperidine-1-carbonyl]-4-methyl-4-[4-(oxetan-3-yl)piperazin-1-yl]pent-2-enenitrile to form a solution;

agitating the solution to form a precipitate; and

isolating crystalline Form A by filtration.

10 - 33 . (canceled)

34 . A pharmaceutical composition comprising:

crystalline Form A of Compound (I) prepared by the process of claim 9 ; and

at least one pharmaceutically acceptable excipient.

35 . The pharmaceutical composition according to claim 34 , wherein the pharmaceutical composition is in the form of a solid oral composition.

36 . The pharmaceutical composition according to claim 34 , wherein the pharmaceutical composition is in the form of a tablet or a capsule.

37 . A method of inhibiting Bruton's tyrosine kinase (BTK) in a mammal comprising administering to the mammal in need of said BTK inhibition a therapeutically effective amount of crystalline Form A of Compound (I) prepared by the process of claim 9 .

38 . A method of treating a disease mediated by Bruton's tyrosine kinase (BTK) in a mammal in need thereof comprising administering to the mammal a therapeutically effective amount of crystalline Form A of Compound (I) prepared by the process of claim 9 .

39 . A method of treating a disease in a mammal in need thereof comprising administering to the mammal a therapeutically effective amount of crystalline Form A of Compound (I) prepared by the process of claim 9 , wherein the disease is chosen from at least one of Pemphigus vulgaris, Pemphigus foliaceus , immune thrombocytopenia, asthma, and dermatitis.

40 . (canceled)

41 . The method of claim 37 , wherein the mammal is a human.

42 . The method of claim 38 , wherein the mammal is a human.

43 . The method of claim 39 , wherein the mammal is a human.
