実験手順

To a solution of 2-methyl-2-(4-methylpiperazin-1-yl)propanal (108.3 mg, 0.6400 mmol) in MeCN (6 mL), was added pyrrolidine (0.11 mL, 1.27 mmol). The reaction mixture was cooled to 0° C., followed by the addition TMS-Cl (0.11 mL, 0.85 mmol). The ice bath was removed and the mixture stirred for 10 min before adding 3-[(2S)-2-[[4-amino-3-(2-fluoro-4-phenoxy-phenyl)pyrazolo[3,4-d]pyrimidin-1-yl]methyl]pyrrolidin-1-yl]-3-oxo-propanenitrile (100 mg, 0.210 mmol). The mixture was stirred for 3 h at room temperature, checking progress by TLC and LC-MS. To the mixture was added 15 ml water and extracted with dichloromethane. The combined organic layer was washed by brine, dried over by Na2SO4, filtered, and evaporated. The residues was loaded on TLC plate and purified using MeOH:CH2Cl2=9:100 to get pure 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-(4-methylpiperazin-1-yl)pent-2-enenitrile (93 mg, 0.1491 mmol, 70.30 2% yield) as a light yellow powder. LC-MS (ES, m/z): 625 [M+H].
