Procedure

To a mixture of (S)-3-(2-((4-amino-3-(2-fluoro-4-phenoxyphenyl)-1H-pyrazolo[3,4-d]pyrimidin-1-yl)methyl)pyrrolidin-1-yl)-3-oxopropanenitrile (285 mg, 0.60 mmol), 2-methyl-2-pyrrolidin-1-yl-propanal (719 mg, 5.1 mmol) and pyrrolidine (0.23 mL, 2.8 mmol) in DCM (6 mL) at room temperature was added chloro(trimethyl)silane (0.23 mL, 1.8 mmol). After stirring 90 min, the solution was diluted with sat. NaHCO3 and extracted with DCM. The organic layers were combined, dried (MgSO4), filtered and concentrated. The crude material was purified by Isolera (10 g column:0%-15% iPrOH/DCM) to obtain 270 mg of (S)-2-(2-((4-amino-3-(2-fluoro-4-phenoxyphenyl)-1H-pyrazolo[3,4-d]pyrimidin-1-yl)methyl)pyrrolidine-1-carbonyl)-4-methyl-4-(pyrrolidin-1-yl)pent-2-enenitrile. MS (pos. ion) m/z: 595 (M+1).
