Procedure

9-Bromo-4-(2-chlorophenyl)-2-ethyl-6H-thieno[3,2-f] [1,2,4]triazolo[4,3-a] [1,4]diazepine is added to 2M sulfuric acid, and the mixture is stirred at 80° C. overnight. Sodium hydrogencarbonate is added to the reaction mixture to make the mixture alkaline. Chloroform and 3,4-dichlorobenzoyl chloride are added, and the mixture is stirred at room temperature for 2 hours to give N-(3-bromo-4-(3-(2-chlorobenzoyl)-5-ethylthiophen-2-yl) [1,2,4]triazol-5-ylmethyl)-3,4-dichlorobenzamide.
