実験手順

To a solution of tert-Butyl N-[2-[[5-[(4-methoxyphenyl)methylcarbamoyl]-1,3-dimethyl-pyrazolo[3,4-b]pyridin-4-yl]amino]ethyl]carbamate (43 mg, 0.092 mmol) in dichloromethane (2.0 ml) was added trifluoromethanesulfonic acid (2.0 mL, 22.60 mmol) and the resulting orange-red mixture was stirred at room temperature over night. The reaction mixture was diluted with dichloromethane (40 ml) and diethylether (100 ml) subsequently upon which a white precipitate was formed. The mixture was stirred for 15 minutes after which the white solids were filtered off, washed with diethylether and dried in a stream of air. 43 mg of an off-white solid was obtained and used directly in the next step. MS (ESI) m/z=249.2.
