Reaction Steps

To a mixture of 8-[3-[N-(4-carboxycinnamoylglycyl)-N-methylamino]-2,6-dichlorobenzyloxy]-2-methylquinoline (100 mg), ethylamine hydrochloride (16.9 mg) and N,N-dimethylformamide (2 ml) were added 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide (32.2 mg) and 1-hydroxybenzotriazole (30.4 mg), and the mixture was stirred for 6 hours at ambient temperature. The mixture was poured into water and extracted with ethyl acetate. The organic layer was washed with water, saturated sodium bicarbonate solution and brine, dried over magnesium sulfate, and concentrated in vacuo. The residue was purified by preparative thin-layer chromatography (methylene chloride-methanol) to give 8-[2,6-dichloro-3-N-[4-(ethylcarbamoyl)cinnamoylglycyl]-N-methylamino]benzyloxy]-2-methylquinoline (91 mg).
