実験手順

3-Aminomethyl-4-(3-(2-chlorobenzoyl)-5-ethylthiophen-2-yl)-5-methyl[1,2,4]triazole di-p-toluenesulfonate (5.0 g) was dissolved in dichloroethane (80 ml). Phenyl isocyanate (0.807 ml) and triethylamine (2.8 ml) were added at room temperature, and the mixture was stirred for 4 hours. Then, the reaction mixture was washed with water and dried over magnesium sulfate. The solvent was evaporated, and the residue was recrystallized from ethyl acetate to give 2.1 g of N-(4-(3-(2-chlorobenzoyl)-5-ethylthiophen-2-yl)-5-methyl[1,2,4]triazol-3-ylmethyl)-N'-phenylurea.
