반응 단계
3-Methyl-4-oxo-thiazolidine-2-thione (403 g) and ethyl orthoformate (1370 ml) were added to acetic anhydride (775 ml), and the mixture was refluxed for 6 hours. The mixture was allowed to stand, and the resulting crystals were collected by filtration and washed with diisopropyl ether to give 342 g of 5-ethoxymethylene-3-methyl-4-oxo-thiazolidine-2-thione.
