실험 절차

To a slurry of 5-(4-acetylbenzyl)thiazolidine-2,4-dione (4.0 mmol, 1.0 g), and benzaldehyde (4.0 mmol, 0.41 ml) in ethanol (10 ml) was added sodium methoxide (4.8 mmol, 260 mg). The solution was heated to reflux for 1.5 hours, then more benzaldehyde was added and the mixture was heated another 1.5 hours, then cooled, diluted with water (60 ml), acidified with 2N HCl and extracted with ethyl acetate (2×50 ml). The combined extracts were washed with water (50 ml), dried over sodium sulfate and concentrated in vacuo. The residue was recrystallized from isopropanol to give title product as a pale yellow solid (0.33 g, 24%); m.p. 147°°149° C.
