Procedure

To a solution of 8-[3-(N-glycyl-N-methylamino)-2,6-dichlorobenzyloxy]-2-methyl-4-(2-pyridylmethoxy)quinoline (30 mg) and 4-(isonicotinamido)cinnamic acid (17 mg) in N,N-dimethylformamide (2 ml) were added 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (14 mg) and 1-hydroxybenzotriazole (11 mg) at ambient temperature, and the mixture was allowed to stand for 1 day at ambient temperature. The reaction mixture was poured into water and extracted with chloroform. The organic layer was washed with water and aqueous sodium hydrogen carbonate solution, dried over magnesium sulfate and evaporated in vacua. The residue was purified by preparative thin layer chromatography (chloroform:methanol=10:1, V/V) to give 8-[2,6-dichloro-3-[N-methyl-N-[4-(isonicotinamido)cinnamoylglycyl]amino]-benzyloxy]-2-methyl-4-(2-pyridylmethoxy)quinoline (19 mg) as an amorphous powder.
