Reaction Steps

590 mg of ethyl [N-[(7-amidino-2-naphthyl)methyl]-N-[4-(hexahydro-1H-1,4-diazepin-1-yl)phenyl]sulfamoyl]-acetate dihydrochloride obtained in Example 6 was dissolved in 22 ml of ethanol, to which were added 680 mg of ethyl acetimidate hydrochloride and 555 mg of triethylamine, and stirred at room temperature for 15 hours. The reaction mixture was evaporated, and the resulting residue was purified through ODS column chromatography using an eluent solvent of ethanol/water (10/90). A small amount of 1 N hydrochloric acid was added to this, which was then freeze-dried to obtain 118 mg of ethyl [N-[4-(4-acetimidoylhexahydro-1H-1,4-diazepin-1-yl)phenyl]-N-[(7-amidino-2-naphthyl)methyl]-sulfamoyl]acetate dihydrochloride.
