実験手順

To a suspension of 5-amino-7-(piperazin-1-yl)-2-(pyridine-3-yl)thiazolo[5,4-d]pyrimidine (150 mg, 0.48 mmol) in dioxane (10 ml) was added 4-tolyl isocyanate (63 μl, 0.5 mmol). The resulting reaction mixture was stirred at room temperature for 30 minutes. The solvents were evaporated in vacuo and the residue was purified by flash chromatography on silica, the mobile phase being a mixture of methanol and dichloromethane (in a ratio of 1/25), yielding the pure title compound as a yellowish solid (170 mg, 79%).
