실험 절차

To 1.8 mL of an ethanol solution containing 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, 0.6 mL of 20% aqueous sodium hydroxide solution was added at room temperature and refluxed with heating for 7 hours. After the reaction mixture was cooled to the room temperature, the solvent was removed under reduced pressure, water was added, adjusted to pH 6.6 with 6.0 mol/L hydrochloric acid. The resulting solid was filtered to give 82 mg of 4-(3-(7-methoxy-2-oxoquinolin-1(2H)-yl)propyl)-1-((2E)-3-phenyl-2-propen-1-yl)piperidine-4-carboxylic acid as a white solid.
