A mixture of 250 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, 125 mg of tert-butyl 3-(methylamino)propanoate, and 2.5 mL of dichloromethane was stirred at room temperature overnight. The reaction mixture was concentrated under reduced pressure and the obtained residue was purified by silica gel column chromatography (hexane-chloroform) to obtain 209 mg of methyl 4-{2-[4-({[2-({3-[(3-tert-butoxy-3-oxopropyl)(methyl)sulfamoyl]benzoyl}amino)-4,5,6,7-tetrahydro-1-benzothiophen-3-yl]carbonyl}amino)phenyl]ethyl}benzoate as a pale yellow foamed solid.
