実験手順

Into a 100 mL round-bottom flask, was placed a solution of tert-butyl (3R)-3-[4-amino-3-[4-(2,5-difluorophenoxy)phenyl]-1H-pyrazolo[3,4-d]pyrimidin-1-yl]piperidine-1-carboxylate (450 mg, 0.86 mmol, 1.00 equiv) in dichloromethane (40 mL). This was followed by the addition of CF3COOH (10 mL) dropwise with stirring at 25° C. over 5 min. The resulting solution was stirred for 3 h at 25° C. and then concentrated under vacuum. The residue was diluted with dichloromethane and the resulting mixture was washed with aqueous sodium bicarbonate and brine and dried over anhydrous sodium sulfate and concentrated under vacuum to give 400 mg (99%) of 3-[4-(2,5-difluorophenoxy)phenyl]-1-[(3R)-piperidin-3-yl]-1H-pyrazolo[3,4-d]pyrimidin-4-amine as a white solid.
