Procedure

To a solution of 5-amino-2-[2-(4-fluorophenyl)ethyl]-7-piperazin-1-yl-thiazolo[5,4-d]pyrimidine (50 mg, 0.14 mmol) in dichloromethane (4 ml) was added 3-methylphenylisocyanate (0.15 mmol). The reaction was stirred at room temperature for 2 hours after which the solvent was removed in vacuo. The resulting residue was purified by flash chromatography on silica, the mobile phase being a mixture of methanol and dichloromethane (in a ratio gradually ranging from 100% CH2Cl2 to 2% CH3OH in CH2Cl2), yielding the pure title compound (28 mg) which was characterized by its mass spectrum: MS m/z (%): 492 ([M+H]+, 100).
