Versuchsvorschrift

A mixture of 319 mg of 3-{ethyl[trans-4-(methoxycarbonyl)cyclohexyl]sulfamoyl}benzoic acid, 0.10 mL of oxalyl chloride, 2.5 mL of dichloromethane, and one drop of DMF was stirred at room temperature for 2 hours, and then the reaction mixture was concentrated under reduced pressure. A mixture of the obtained crude product and 2.5 mL of dichloromethane was added to a mixture of 0.050 mL of pyridine, 250 mg of methyl 4-[2-(4-{[(2-amino-4,5,6,7-tetrahydro-1-benzothiophen-3-yl)carbonyl]amino}phenyl)ethyl]benzoate, and 2.5 mL of dichloromethane, followed by stirring at room temperature overnight. The reaction mixture was purified by silica gel column chromatography (hexane-chloroform) to obtain 320 mg of methyl 4-(2-{4-[({2-[(3-{ethyl[trans-4-(methoxycarbonyl)cyclohexyl]sulfamoyl}benzoyl)amino]-4,5,6,7-tetrahydro-1-benzothiophen-3-yl}carbonyl)amino]phenyl}ethyl)benzoate as a yellow foamed solid.
