Procedure

To a solution of 4N HCl in dioxane (0.5 mL, 0.050 mmol) in THF (1 mL) in the ice bath, was added tert-butyl 4-[4-[(2S)-2-[[4-amino-3-(2-fluoro-4-phenoxy-phenyl)pyrazolo[3,4-d]pyrimidin-1-yl]methyl]pyrrolidin-1-yl]-3-cyano-1,1-dimethyl-4-oxo-but-2-enyl]piperazine-1-carboxylate (32.9 mg, 0.050 mmol). The ice bath was removed, the reaction mixture was stirred for 4 h at room temperature at which point TLC and LC-MS showed the reaction was finished. The mixture was concentrated in vacuo, adjusted with NaHCO3 to pH 6-7, and the aq. layer extracted with CH2Cl2. The combined organic layer was washed by brine, dried over Na2SO4, filtered, and the solvent removed to get product 2-[(2S)-2-[[4-amino-3-(2-fluoro-4-phenoxy-phenyl)pyrazolo[3,4-d]pyrimidin-1-yl]methyl]-pyrrolidine-1-carbonyl]-4-methyl-4-piperazin-1-yl-pent-2-enenitrile (24 mg, 0.039 mmol, 85% yield) as an off white powder. LC-MS (ES, m/z): 610 [M+H]
