Reaction Steps

9-Aminomethyl-4-(2-chlorophenyl)-2-ethyl-6H-thieno[3,2-f] [1,2,4]triazolo[4,3-a] [1,4]diazepine (0.28 g) and triethylamine (0.115 ml) were dissolved in dichloroethane (15 ml). 3,4-Dichlorobenzoyl chloride (0.17 g) was added at room temperature, and the mixture was stirred for 1 hour. The reaction mixture was concentrated, and the residue was purified by silica gel column chromatography using a mixed solvent of ethyl acetate and methanol as a developing solvent. The obtained solid was recrystallized from a mixed solvent of ethyl acetate and hexane to give 0.27 g of N-(4-(2-chlorophenyl)-2-ethyl-6H-thieno[3,2-f] [1,2,4]triazolo[4,3-a] [1,4]diazepin-9-ylmethyl)-3,4-dichlorobenzamide.
