Procedure

Cis-3-{4-[4-(aminomethyl)phenoxy]phenyl}-1-[4-(4-methylpiperazino)cyclohexyl]-1H-pyrazolo[3,4-d]pyrimidin-4-amine (0.051 g, 0.0001 mol) was dissolved in anhydrous pyridine (1 mL), benzyl isocyanate (0.013 g, 0.0001 mol) was added and the resulting solution was stirred at ambient temperature for twenty hours. The solvent was removed under reduced pressure and the resulting residue purified by preparative HPLC (Hypersil C 18, 8 μm, 25 cm; 10-60% acetonitrile-0.1M ammonium acetate over 25 min, 21 mL/min) to yield cis-N-[4-(4-{4-amino-1-[4-(4-methylpiperazino)cyclohexyl]-1H-pyrazolo[3,4-d]pyrimidin-3-yl}phenoxy)benzyl]-N′-benzylurea acetate (0.019 g, 0.000027 mol) as a white solid.
