Reaction Steps
3,5-di-(2-propenyl)-4-hydroxybenzaldehyde (50.5 g), 36.6 g of rhodanine and 164 g of sodium acetate were heated together at reflux temperature in 1.25 liter of acetic acid for 14.5 hours. The resultant solution was cooled, poured into 2 l of ice water to yield, upon separation, about 75 g of 5-[(3,5-di-2-propenyl-4-hydroxyphenyl)methylene]-2-thioxo-4-thiazolidinone, m.p. 157°-160° C.
