Reaction Steps

To a suspension of 5.20 g of 5-(ethoxymethylene)thiazolidine-2,4-dione (1:1.71 mixture with thiazolidine-2,4-dione, about 13.9 mmol) in 50 ml of ethanol, 5.0 g (59 mmol) of ethanethiol sodium salt was added at room temperature, followed by stirring under heating conditions for 3 hours. After cooling, the reaction mixture was poured into water and adjusted to a pH level of about 2. The resulting precipitate was collected by filtration, washed with water and then with n-hexane/diethyl ether and dried to yield 1.38 g (52.0%, light yellow powder) of the desired product.
