To a solution of (4-{3-[2-(3-chloro-benzylamino)-pyrimidin-4-yl]-1H-pyrazolo[3,4-d]pyrimidin-6-ylamino}-cyclohexyl)-carbamic acid tert-butyl ester (30 mg, 0.0548 mmol) in methanol (30 mL) was bubbled in HCl (gas) for 3 hours at room temperature. The mixture was concentrated by evaporation to afford N-{3-[2-(3-chloro-benzylamino)-pyrimidin-4-yl]-1H-pyrazolo[3,4-d]pyrimidin-6-yl}-cyclohexane-1,4-diamine; hydrochloride. (Yield 29 mg, 98.0%).
