Procedure

To a solution of tert-butyl N-[4-[[(1R)-2-[4-amino-3-(2-fluoro-4-phenoxy-phenyl)pyrazolo[3,4-d]pyrimidin-1-yl]-1-methyl-ethyl]amino]-3-cyano-1,1-dimethyl-4-oxo-but-2-enyl]carbamate (71 mg, 0.12 mmol) in methanol (1 mL) was added 4N HCl in Dioxane (2 mL). The solution was stirred for 4 days and then it was added dropwise to stirring ethyl ether (70 mL). The suspension was stirred for 30 minutes and then filtered and rinse with ethyl ether (10 mL) to obtain 57 mg (95%) of the title compound as an HCl salt.
