To 2.5 mL of an N,N-dimethylformamide solution containing 0.10 g of ethyl 4-(3-(7-methoxy-2-oxoquinolin-1(2H)-yl)propyl)piperidine-4-carboxylate, 74 mg of potassium carbonate and 69 mg of 1-(3-fluorophenyl)thio-2-bromoethane were added at room temperature, and stirred at 60° C. for 4 hours. After the reaction mixture was cooled to room temperature, ethyl acetate and water were added. The organic layer was separated, washed with aqueous saturated sodium chloride solution, dried over anhydrous magnesium sulfate, and the solvent was removed under reduced pressure. The residue thus obtained was purified by silica gel column chromatography [eluent; chloroform : methanol=10:1], to give 95 mg of ethyl 1-(2-((3-fluorophenyl)thio)ethyl)-4-(3-(7-methoxy-2-oxoquinolin-1(2H)-yl)propyl)piperidine-4-carboxylate as a yellow oil.
