To a mixture of 8-[3-(N-glycyl-N-methylamino)-2,6-dichlorobenzyloxy]-2-methylquinoline (100 mg), (E)-3-(6-acetamidopyridin-3-yl)acrylic acid (56.1 mg) and N,N-dimethylformamide (2 ml) were added 1-hydroxybenzotriazole (43.4 mg) and 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (56.9 mg) in a nitrogen stream at 0° C., and the resulting mixture was stirred at ambient temperature for 2 hours. The reaction mixture was poured into water, and extracted with chloroform. The organic layer was washed with an aqueous solution of saturated sodium hydrogencarbonate, water and brine successively, and dried over magnesium sulfate, and thereafter the solvent was removed under reduced pressure. The residue was purified by preparative thin-layer chromatography (methanol:dichloromethane=1:10, v/v), and solidified with diethyl ether and ethyl acetate to give 8-[3-[N-[(E)-3-(6-acetamidopyridin-3-yl)acryloylglycyl]-N-methylamino]-2,6-dichlorobenzyloxy]-2methylquinoline (FR173657) (78.8 mg) as a grayish white solid.
