Procedure

To a solution of 5-amino-2-[2-(4-fluorophenyl)ethyl]-7-piperazin-1-yl-thiazolo[5,4-d]pyrimidine (80 mg, 0.22 mmol) in 1,4-dioxane (4 ml) was added diisopropylethylamine (0.49 mmol, 81 μL) and phenylmethanesulfonyl chloride (0.25 mmol). The reaction was stirred at 90° C. for 16 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 1% CH3OH in CH2Cl2), yielding the pure title compound (13 mg) which was characterized by its mass spectrum: MS m/z (%): 513 ([M+H]+, 100).
