Procedure

350 mg of 5-(8-methoxy-1-methyl-2-oxo-1,2-dihydroquinolin-5-ylmethyl)thiazolidine-2,4-dione was dissolved in 5 ml of DMF. 0.156 ml of methyl bromoacetate and 0.25 g of potassium carbonate were added to the solution, followed by stirring at room temperature overnight. Water was added, and the mixture was extracted with methylene chloride. The organic layer was washed with saturated sodium chloride solution, and dried over sodium sulfate. After filtration, the solvent was distilled off under reduced pressure. The residue was purified by silica gel chromatography and recrystallized from methanol-acetone, giving 245 mg (57% yield) of 3-methoxycarbonylmethyl-5-(8-methoxy-1-methyl-2-oxo-1,2-dihydroquinolin-5-ylmethyl)thiazolidine-2,4-dione as white crystals.
