Procedure

A mixture of (R)-3-(3-(4-amino-3-(2-fluoro-4-phenoxyphenyl)-1H-pyrazolo[3,4-d]pyrimidin-1-yl)piperidin-1-yl)-3-oxopropanenitrile (150 mg, 0.31 mmol), 2-(4-hydroxy-1-piperidyl)-2-methyl-propanal (167 mg, 0.98 mmol), pyrrolidine (0.03 mL, 0.31 mmol) and DCM (10 mL) was stirred at room temp for 2 days and then diluted with aq. NaHCO3 (40 mL) and extracted with DCM. The organic was dried (MgSO4), filtered and concentrated to an oil. The crude material was purified at Isolera (25 g column: 30% iPrOH/DCM) to obtain the product which was isolated by lyophilization to provide 61 mg (32% yield) of (R)-2-(3-(4-amino-3-(2-fluoro-4-phenoxyphenyl)-1H-pyrazolo[3,4-d]pyrimidin-1-yl)piperidine-1-carbonyl)-4-(4-hydroxypiperidin-1-yl)-4-methylpent-2-enenitrile as a powder. MS (pos. ion) m/z: 625 (M+1).
