Procedure

Trans-3-(4-[(2-methoxy-3-pyridyl)methyl]aminophenyl)-1-[4-(4-methylpiperazino)cyclohexyl]-1H-pyrazolo[3,4-d]pyrimidin-4-amine diacetate (0.105 g, 0.000199 mol) was dissolved in 30% hydrogen bromide in acetic acid (4 mL) and the mixture was refluxed for 1.5 hours. The solvent was removed under reduced pressure and the residue was purified by preparative HPLC (Hypersil C18, 8 μm, 25 cm; 10-60% acetonitrile-0.1M ammonium acetate over 25 min, 21 mL/min) to yield trans-3-[(4-{4-amino-1-[4-(4-methylpiperazino)cyclohexyl]-1H-pyrazolo[3,4-d]pyrimidin-3-yl}anilino)methyl]-1,2-dihydro-2-pyridinone diacetate (0.0204 g, 0.0000324 mol) as a white solid.
