Reaction Steps

1-Dodecanol (0.10 g) was dissolved in anhydrous THF (5 ml) under a nitrogen atmosphere and sodium hydride (about 55% oil) (25 mg) was added under ice-cooling with stirring. The reaction mixture was stirred at room temperature for 30 min under a nitrogen atmosphere, and then the mixture was ice-cooled. To the mixture was added a solution (5 ml) of carbonic acid 7-[4-(4-benzo[b]thiophen-4-ylpiperazin-1-yl)butoxy]-2-oxo-2H-quinolin-1-ylmethyl ester 4-nitrophenyl ester obtained in Example 133 (0.33 g) in anhydrous THF using a cannula. Under a nitrogen atmosphere, the reaction mixture was stirred with ice-cooling for 2 hr, and at room temperature for 1 hr. Water was added to the reaction mixture to discontinue the reaction, and the mixture was extracted with ethyl acetate. The organic layer was dried over sodium sulfate, and concentrated by filtration. The obtained residue was purified by silica gel column chromatography (ethyl acetate:hexane=1:1) to give the title compound (0.14 g) as a colorless oil.
