Versuchsvorschrift

Into a 100 mL, round-bottom flask, was placed a solution of tert-butyl (2R)-2-([4-amino-3-[4-(3,5-difluorophenoxy)phenyl]-1H-pyrazolo[3,4-d]pyrimidin-1-yl]methyl)pyrrolidine-1-carboxylate (230 mg, 0.44 mmol, 1.00 equiv) in dichloromethane (50 mL). This was followed by the addition of trifluoroacetic acid (10 mL) dropwise with stirring over 10 min. The resulting solution was stirred for 3 h at 25° C. The resulting mixture was concentrated under vacuum to give 0.185 g (crude) of 3-[4-(3,5-difluorophenoxy)phenyl]-1-[(2R)-pyrrolidin-2-ylmethyl]-1H-pyrazolo[3,4-d]pyrimidin-4-amine as a brown oil.
