To 22.3 g of succinic acid, 24.0 g of 6-amidino-2-naphthyl 5-aminomethylfuran-2-carboxylate dihydrochloride and 790 mg of DMAP was added 240 ml of pyridine, and the mixture was stirred while cooling with ice. After 10 minutes, 25.9 g of DCC was added and the mixture was stirred for 3 hours while cooling with ice and then for 16 hours at room temperature. The precipitate was filtered off, and the filtrate was added in small portions into 2 l of ether and stirred at room temperature for 3 hours.
