Procedure

3-Aminomethyl-4-(3-(2-chlorobenzoyl)-5-ethylthiophen-2-yl)-5-methyl[1,2,4]triazole di-p-toluenesulfonate (3.70 g) was dissolved in dichloroethane (20 ml). Benzoyl chloride (0.64 ml) and triethylamine (2.8 ml) were added to the solution under ice-cooling, and the mixture was stirred at room temperature overnight. A saturated aqueous sodium hydrogencarbonate solution was added to the reaction mixture, and the mixture was extracted with chloroform. The organic layer was washed with saturated brine and dried over magnesium sulfate. The solvent was evaporated. The residue was purified by silica gel column chromatography (developing solvent:chloroform-methanol), and recrystallized from ethyl acetate to give 1.50 g of N-(4-(3-(2-chlorobenzoyl)-5-ethylthiophen-2-yl)-5-methyl[1,2,4]triazol-3-ylmethyl)benzamide.
