Versuchsvorschrift

To a solution of 8-[2,6-dichloro-3-(piperazine-1-carbonyl)benzyloxy]-2-methylquinoline dihydrochloride (60 mg), 4-(methylcarbamoyl)cinnamic acid (26.9 mg) and 1-hydroxybenzotriazole (22.6 mg) in N,N-dimethylformamide (0.6 ml) was added 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide (27.4 mg) at ambient temperature, and the mixture was stirred for 3 hours at the same temperature. The reaction mixture was poured into water and extracted with ethyl acetate. The extract was washed with saturated sodium bicarbonate solution, water and brine, dried over magnesium sulfate and evaporated in vacuo. The residue was purified by preparative thin layer chromatography (chloroform:methanol=10:1, V/V) to give 8-[2,6-dichloro-3-[4-[4-(methylcarbamoyl)cinnamoyl]piperazine-1-carbonyl]benzyloxy]-2-methylquinoline (73 mg) as colorless amorphous.
