A mixture of tert-butyl 3-[4-amino-3-(4-phenoxyphenyl)-1H-pyrazolo[3,4-d]pyrimidin-1-yl]piperidine-1-carboxylate (700 mg, 1.44 mmol, 1.00 equiv) in dichloromethane (100 mL) and trifluoroacetic acid (20 mL) was stirred at room temperature for 12 h. The reaction mixture was concentrated under vacuum to yield 580 mg of crude 3-(4-phenoxyphenyl)-1-(piperidin-3-yl)-1H-pyrazolo[3,4-d]pyrimidin-4-amine as a yellow oil.
