Reaction Steps

1.5 g of N1-(5-formyl-2-methoxybenzyl)-4-(trifluoromethyl)benzamide was dissolved in 15 ml toluene, and 0.52 g of 2,4-thiazolidine dione, 36 mg pyrrolidine and 30 mg acetic acid were added thereto, and the mixture was heated under reflux for 2 hours with a Dean-Stark apparatus. After cooling to room temperature, the precipitated crystals were collected by filtration, washed with ethyl acetate and then dried, to give 1.4 g of N1-[5-[(2,4-dioxo-1,3-thiazolane-5-ylidene)methyl]-2-methoxybenzyl)-4-(trifluoromethyl)benzamide.
