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 (150 mg, 0.27 mmol) in ethanol (5 mL) was added concentrated hydrochloric acid (3 mL) slowly. The reaction mixture was stirred at room temperature for 15 hours. The solvent was then removed under reduced pressure and the solid was purified by prep-HPLC and concentrated 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 25 mg, 20.3%).
