To a stirred solution of (4-{3-[3-(3-tert-butoxycarbonylamino-1-phenyl-propylamino)-phenyl]-1-trityl-1H-pyrazolo[3,4-d]pyrimidin-6-ylamino}-cyclohexyl)-carbamic acid tert-butyl ester (91 mg, 0.10 mmol) in EtOH (2.0 mL) was added conc. HCl (4 mL) at room temperature. The resulting mixture was stirred for 15 hours at room temperature. The reaction solution was concentrated under reduced pressure. The residue was washed with dichloromethane (10 mL), then purified by prep-HPLC to give N-{3-[3-(3-amino-1-phenyl-propylamino)-phenyl]-1H-pyrazolo[3,4-d]pyrimidin-6-yl}-cyclohexane-1,4-diamine; hydrochloride. (Yield 43 mg).
