Synthesis of methyl 4-aryl-2-{[4-(carbamimidoylsulfamoyl)- phenyl]amino}-4-oxobut-2-enoates

Methyl aroylpyruvates reacted with 4-amino- N -carbamimidoylbenzene-1-sulfonamide in acetic acid–ethanol (1: 1) to give methyl 4-aryl-2-{[4-(carbamimidoylsulfamoyl)phenyl]amino}-4-oxobut-2-enoates which were found to exist in solution as mixtures of Z and E isomers.
