Cis-3-{4-[amino(phenyl)methyl]phenyl}-1-[4-(4-methylpiperazino)cyclohexyl]-1H-pyrazolo[3,4-d]pyrimidin-4-amine (0.05 g, 0.0001 mol) and β-butyrolactone (0.009 g, 0.0001 mol) were heated in dioxane at reflux for three hours. The solvent was removed under reduced pressure and the resulting residue 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 cis-N1-[(4-{4-amino-1-[4-(4-methylpiperazino)cyclohexyl]-1H-pyrazolo[3,4-d]pyrimidin-3-yl}phenyl)(phenyl)methyl]-3-hydroxybutanamide acetate (0.027 g, 0.000042 mol) as a white solid.
