Procedure

912 mg of 2-chloro-4-(8-methoxy-1-methyl-2-oxo-1,2-dihydroquinolin-5-yl)butyric acid, 390 mg of thiourea, and 394 mg of sodium acetate were added to 20 ml of methoxyethanol, followed by stirring at 110° C. for 4 hours. The reaction mixture was concentrated under reduced pressure. Water was added to the residue, and the mixture was extracted with dichloromethane. The extract was dried over anhydrous sodium sulfate and concentrated. The residue was added to a mixed solvent of 10 ml of 10% hydrochloric acid and 10 ml of ethanol, followed by heating and refluxing overnight. The solvent was distilled off under reduced pressure, and the residue was recrystallized from a DMF-ethanol mixed solvent, giving 332 mg (31% yield) of 5-[2-(8-methoxy-1-methyl-2-oxo-1,2-dihydroquinolin-5-yl)ethyl]thiazolidine-2,4-dione as a yellow powder.
