To a solution of 4-{3-[2-(3-chloro-benzylamino)-pyrimidin-4-yl]-1H-pyrazolo[3,4-d]pyrimidin-6-ylamino}-piperidine-1-carboxylic acid tert-butyl ester (80 mg, 0.15 mmol) in EtOH (4 mL) was added conc. HCl (4 mL). The reaction mixture was stirred at room temperature for 15 hours. The solvent was then removed and the residue was purified by prep-HPLC to afford {3-[2-(3-chloro-benzylamino)-pyrimidin-4-yl]-1H-pyrazolo[3,4-d]pyrimidin-6-yl}-piperidin-4-yl-amine; hydrochloride. (Yield 20 mg, 26.3%).
