Procedure

The (2S,6R)-tert-butyl 4-(5-((R)-3-(4-amino-3-(2-fluoro-4-phenoxyphenyl)-1H-pyrazolo[3,4-d]pyrimidin-1-yl)piperidin-1-yl)-4-cyano-2-methyl-5-oxopent-3-en-2-yl)-2,6-dimethylpiperazine-1-carboxylate (103.5 mg, 0.1400 mmol) was dissolved in 4N HCl in dioxane, and stirred at rt for 3 hours. The solvent was removed and 2 mL of MeOH was added to the residues. The mixture was neutralized to pH around 7-8 and extracted with DCM. The combined organic layer was washed with brine, dried over sodium sulfate, filtered, and the solvent evaporated to get pure product 2-((R)-3-(4-amino-3-(2-fluoro-4-phenoxyphenyl)-1H-pyrazolo[3,4-d]pyrimidin-1-yl)piperidine-1-carbonyl)-4-((3S,5R)-3,5-dimethylpiperazin-1-yl)-4-methylpent-2-enenitrile as a white solid. MS (pos. ion) m/z: 638 (M+1).
