To a solution of n-hexylalcohol (50.5 mg) in tetrahydrofuran (5 ml) was added with stirring under ice-cooling 60% sodium hydride (18 mg) by small portions, and the mixture was stirred at the same temperature for 0.5 hr, to a solution of carbonic acid 7-[4-(4-benzo[b]thiophen-4-ylpiperazin-1-yl)butoxy]-2-oxo-2H-quinolin-1-ylmethyl ester phenyl ester (240 mg) in tetrahydrofuran (1 ml) was added with stirring under ice-cooling sodium methoxide (30 mg), and the mixture was stirred for 3 hr. Water was added to the reaction mixture, and the mixture was extracted with ethyl acetate, and dried over sodium sulfate. The solvent was evaporated under reduced pressure and the residue was purified by silica gel column chromatography (ethyl acetate) to give carbonic acid 7-[4-(4-benzo[b]thiophen-4-ylpiperazin-1-yl)butoxy]-2-oxo-2H-quinolin-1-ylmethyl ester methyl ester (42 mg).
