1-Heptanethiol (250 mg) was dissolved in methanol (5 mL), to which a solution of 28% sodium methoxide in methanol (0.37 mL) was then added, followed by stirring at room temperature for 15 minutes. The reaction mixture was added to a solution of p-toluenesulfonic acid [4-(benzyloxy)-3-methylquinolin-2-yl]methyl ester (464 mg) in methanol-THF (1:1, 10 mL), followed by stirring at room temperature for 30 minutes. The reaction mixture was concentrated under reduced pressure, and water (100 mL) was added to the resulting residue, followed by extraction with ethyl acetate (100 mL). The organic layer was washed with saturated brine, and then dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure, and the residue was purified by silica gel column chromatography (eluent: hexane/ethyl acetate=5/1) to obtain 4-(benzyloxy)-2-[(heptylsulfanyl)methyl]-3-methylquinoline (380 mg).
