Reaction Conditions

Reaction Steps

A mixture of 19.6 g of 3,4,5-trimethoxybenzaldehyde, 10.6 g of 2-mercaptopropionic acid and 6 g of ammonium carbonate in 250 ml of benzene was refluxed for 3 hours at 80° C. in a flask provided with a Dean-Stark apparatus and the thus distilled water was removed. The crystals which separated out from the reaction mixture after reaction was over and on cooling the reaction mixture, were collected by filtration and recrystallized from benzene to give 22.2 g of colourless and aciculates melting at 133° to 134° C. in a yield of 78%.
