To a solution of 1.0 g of ethyl 4-amino-2-(methylsulfanyl)pyrimidine-5-carboxylate in 15 mL of N,N-dimethylformamide, 315 mg of sodium hydride was added, and the resulting mixture was stirred at room temperature for 5 minutes. To the reaction mixture, 970 mg of 2,6-dichlorophenyl isocyanate was added, and the resulting mixture was stirred at room temperature for 1 hour. To the reaction mixture, ethyl acetate and a 1 N aqueous hydrochloric acid solution were added and the organic layer was separated. The organic layer was washed with saturated saline and dried over anhydrous sodium sulfate, and then, the solvent was distilled off. The precipitated solid was solidified with methanol and collected by filtration, whereby 1.43 g of the title compound was obtained as a white solid.
