Reaction Conditions

Reaction Steps

A mixture of 13.6 g of o-anisaldehyde, 10.6 g of 3-mercaptopropionic acid and 6 g of ammonium carbonate in 250 ml of toluene was refluxed at 110° C. for 2 hours in a flask provided with a Dean-Stark apparatus while removing the distilled water. The crystals which separated out after leaving the reaction mixture for a night were collected by filtering and recrystallized from hot dimethylformamide to obtain the object, colourless prisms melting at 201.5° to 203° C. in an amount of 18.7 g corresponding to a yield of 84%.
