Reaction Steps

Cis-3-(4-amino-3-methoxyphenyl)-1-[4-(4-methylpiperazino)cyclohexyl]-1H-pyrazolo[3,4-d]pyrimidin-4-amine (0.082 g, 0.000188 mol) was dissolved in anhydrous pyridine (1 mL), benzyl isocyanate (0.025 g, 0.000188 mol) was added and the resulting solution was stirred at ambient temperature for 20 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-amino-1-[4-(4-methylpiperazino)cyclohexyl]-1H-pyrazolo[3,4-d]pyrimidin-3-yl}-2-methoxyphenyl)-N′-benzylurea acetate (0.009 g, 0.0000142 mol) as a white solid.
