Versuchsvorschrift

To a solution of 4-(benzyloxy)-2-[(heptylsulfanyl)methyl]-3-methylquinoline (150 mg) in trifluoroacetic acid (5 mL) was added thioanisole (150 mg), followed by stirring at room temperature for 16 hours. The reaction mixture was added dropwise to an ice-cold aqueous sodium hydrogen carbonate solution, followed by extraction with ethyl acetate (50 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: chloroform/methanol=10/1) to obtain 2-[(heptylsulfanyl)methyl]-3-methylquinolin-4(1H)-one (110 mg).
