Into a 100 mL, round-bottom flask, was placed a solution of tert-butyl (2R)-2-[[4-amino-3-(2-fluoro-4-phenoxyphenyl)-1H-pyrazolo[3,4-d]pyrimidin-1-yl]methyl]pyrrolidine-1-carboxylate (347 mg, 0.69 mmol, 1.00 equiv) in dichloromethane (50 mL). Trifluoroacetic acid (10 mL) dropwise with stirring over 10 min and the resulting solution was stirred for 3 h at 25° C. The resulting mixture was concentrated under vacuum to give 0.278 g (crude) of 3-(2-fluoro-4-phenoxyphenyl)-1-[(2R)-pyrrolidin-2-ylmethyl]-1H-pyrazolo[3,4-d]pyrimidin-4-amine as brown oil.
