実験手順

Benzaldehyde (0.78 mol, 82.8 g) and 2,4-thiazolidinedione (0.85 mol, 100 g) were heated to reflux in a mixture of pyridine (215 ml) and dimethylformamide (400 ml) for 18 hours. The reaction mixture was cooled to 55° C. and diluted with hexane (360 ml) and water (900 ml) and stirred for 1 hour after cooling to room temperature. The product was collected to afford 175 g of pale yellow solid; m.p. 246°-248° C.
