실험 절차

A mixture of 2-methylthio-4-(3-chloro-4-methoxybenzylamino)-5-carboxypyrimidine (prepared in Example 79) 0.100 g and triethylamine 82 μl in tetrahydrofuran 2.0 ml is treated under room temperature with 2,4,6-trichlorobenzoyl chloride 51 μl and then dimethylaminopyridine about 1 mg is added thereto, followed by stirring for 10 minutes. After addition of 2-pyridinemethanol 31 μl, the mixture is stirred for 12 hours. Ethyl acetate and water are added thereto and the organic layer is separated, washed with sodium hydrogen carbonate solution, brine. The organic layer is dried over anhydrous sodium sulfate and in vacuo. The residue is purified with silica gel chromatography (solvent; chloroform:ethyl acetate=5:1–2:1) and recrystallized from ethyl acetate-isopropyl ether to give 2-methylthio-4-(3-chloro-4-methoxybenzylamino)-5-(2-pyridylmethoxycarbonyl)pyrimidine as a colorless needle, 0.5183 g. mp117–118° C.
