실험 절차

Cis-tert-butyl N-[(4-{4-amino-1-[4-(4-methylpiperazino)cyclohexyl]-1H-pyrazolo[3,4-d]pyrimidin-3-yl}phenyl)(phenyl)methyl]carbamate (2.05 g, 0.00344 mol) was triturated in anhydrous dichloromethane (50 mL) and the reaction mixture was cooled to 0° C. Trifluoroacetic acid (10 mL) was added dropwise and the resulting solution was warmed up to ambient temperature and stirred under an atmosphere of nitrogen for one and a half hour. The solvents were removed under reduced pressure, the residue suspended in water (50 mL) and basified with saturated aqueous sodium bicarbonate solution. It was extracted with dichloromethane (3×150 mL), the combined organic extracts were dried with magnesium sulfate and the solvent was removed under reduced pressure to yield cis-3-{4-[amino(phenyl)methyl]phenyl}-1-[4-(4-methylpiperazino) cyclohexyl]-1H-pyrazolo[3,4-d]pyrimidin-4-amine (1.60 g, 0.00322 mol) as an off-white solid.
