Procedure

To an ice-cooled mixture of sodium hydride (40% in oil, 9 mg) and anhydrous N,N-dimethylformamide (1 ml) was added 8-hydroxy-2-methyl-4-(2-pyridylmethoxy)quinoline (53 mg), and the mixture was stirred at the same temperature for 30 minutes. To this mixture was added 2,6-dichloro-3-[N-[4-(methylcarbamoyl)cinnamoylglycyl]-N-methylamino]benzyl bromide (103 mg), and the mixture was stirred at ambient temperature for 2.5 hours. Water (2 ml) was slowly added to the reaction mixture under ice-water cooling and the precipitates were collected by vacuum filtration and washed with water and diethyl ether. The crude product was purified by a preparative thin layer chromatography (chloroform-methanol-ammonium hydroxide) followed by trituration with ethyl acetate to give 8-[2,6-dichloro-3-[N-[4-(methylcarbamoyl)cinnamoylglycyl]-N-methylamino]benzyloxy]-2-methyl-4-(2-pyridylmethoxy)quinoline (77 mg) as a pinkish powder.
