A mixture of 600 mg of methyl 4-[2-(4-{[(2-{[3-(chlorosulfonyl)benzoyl]amino}-4,5,6,7-tetrahydro-1-benzothiophen-3-yl)carbonyl]amino}phenyl)ethyl]benzoate, 394 mg of ethyl 4-aminobutyrate hydrochloride, 0.27 mL of triethylamine, and 6.0 mL of dichloromethane was stirred at room temperature for 2 hours. The reaction mixture was purified by silica gel column chromatography (hexane-chloroform) to obtain 442 mg of methyl 4-{2-[4-({[2-({3-[(4-ethoxy-4-oxobutyl)sulfamoyl]benzoyl}amino)-4,5,6,7-tetrahydro-1-benzothiophen-3-yl]carbonyl}amino)phenyl]ethyl}benzoate as a pale yellow solid.
