Vorschrift

To 1.25 mL of an N,N-dimethylformamide solution containing 70 mg of ethyl 4-(3-(7-methoxy-2-oxoquinolin-1(2H)-yl)propyl)piperidine-4-carboxylate, 57 mg of potassium carbonate and 0.25 mL of an N,N-dimethylformamide solution containing 31 μL of (3-bromopropyl)benzene were added at room temperature, and stirred at 60-75° C. for 1.5 hours. After the reaction mixture was cooled to the room temperature, ethyl acetate and water were added. The organic layer was separated, and the mixture was washed sequentially with water and aqueous saturated sodium chloride solution, dried over anhydrous magnesium sulfate, and the solvent was removed under reduced pressure to give 81 mg of ethyl 4-(3-(7-methoxy-2-oxoquinolin-1(2H)-yl)propyl)-1-(3-phenylpropyl)piperidine-4-carboxylate as a yellow oil.
