Participants

Reaction Steps

To a solution of tert-butyl (2S)-2-[[4-amino-3-(2-fluoro-4-phenoxyphenyl)-1H-pyrazolo[3,4-d]pyrimidin-1-yl]methyl]-4,4-difluoropyrrolidine-1-carboxylate (600 mg, 1.11 mmol, 1.00 equiv) in dichloromethane (10 mL) was added trifluoroacetic acid (2 mL) dropwise. The resulting solution was stirred at room temperature for 2 h. The mixture was concentrated under vacuum to give 0.85 g (crude) of 1-[[(2S)-4,4-difluoropyrrolidin-2-yl]methyl]-3-(2-fluoro-4-phenoxyphenyl)-1H-pyrazolo[3,4-d]pyrimidin-4-amine trifluoroacetic acid salt as a brown semi-solid.
