Reaction Steps

15 Milliliters of 20% hydrous pyridine was added to 634.1 mg of 3-[(4,5-dihydro-1H-imidazol-2-yl)amino]benzoic acid.hydrochloride, 676.7 mg of 6-amidino-1-carbamoylmethyl-2-naphthol.hydrochloride, 598 mg of DCC and 29.5 mg of DMAP, followed by stirring for 2 hours under cooling with ice and then 24 hours under cooling with water. Thereafter, the same procedure as in Example 1 was carried out to obtain 439.5 mg of the desired product.
