Procedure

To a solution of tert-butyl (2S)-2-[3-[(2R)-2-[[4-amino-3-(2-fluoro-4-phenoxy-phenyl)pyrazolo[3,4-d]pyrimidin-1-yl]methyl]pyrrolidin-1-yl]-2-cyano-3-oxo-prop-1-enyl]pyrrolidine-1-carboxylate (84 mg, 0.13 mmol) in 1,4-dioxane (2 mL) and added 4N HCl in dioxane (0.16 mL). The solution was stirred for 16 hr at room temperature then concentrated. The residue was dissolved in methanol (˜1 mL) and added dropwise to ethyl ether (20 mL) while stirring. The resulting solid was collected by filtration to provide 42 mg (59%) of the title compound as an HCl salt. MS (pos. ion) m/z: 553 (M+1).
