Procedure

To 3 mL of an N,N-dimethylformamide solution containing 0.10 g of ethyl 4-(3-(7-methoxy-2-oxo-1,2-dihydroquinolin-1-yl)propyl)piperidine-4-carboxylate, 0.11 g of potassium carbonate, 41 μL of ((1E)-3-chloro-1-propenyl)benzene and 45 mg of potassium iodide were added at room temperature and stirred for 4.5 hours. To the reaction mixture, water and ethyl acetate 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=35:1], to give 0.11 g of ethyl 4-(3-(7-methoxy-2-oxoquinolin-1(2H)-yl)propyl)-1-((2E)-3-phenyl-2-propen-1-yl)piperidine-4-carboxylate as a yellow oil.
