Procedure

To 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 (222 mg, 0.46 mmol), 2-methyl-2-(6-oxa-2-azaspiro[3.3]heptan-2-yl)propanal (231.17 mg, 1.37 mmol) and pyrrolidine (0.23 mL, 2.73 mmol) in DCM (10 mL) at room temperature was added chloro(trimethyl)silane (0.17 mL, 1.37 mmol). After stirring 2 h, 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 chromatography to obtain 133 mg of 2-[(3R)-3-[4-amino-3-(2-fluoro-4-phenoxy-phenyl)pyrazolo[3,4-d]pyrimidin-1-yl]piperidine-1-carbonyl]-4-methyl-4-(6-oxa-2-azaspiro[3.3]heptan-2-yl)pent-2-enenitrile. MS (pos. ion) m/z: 623 (M+1).
