Reaction Conditions

Reaction Steps

In 150 ml of ethanol is dissolved 10 g of ethyl 3-(4-thianyl)acrylate, and a catalytic reduction reaction is carried out at ordinary temperature and at atmospheric pressure using 9 g of 10% palladium-carbon (50% in water) as a catalyst. The reaction mixtuure is stirred at room temperature for 20 minutes and at 50° C. for 8 hours, and the catalyst is removed by filtration. Nine (9) g of 10% palladium-carbon (50% in water) is added anew to the filtrate, followed by stirring at 50° C. for one day. The catalyst is removed by filtration, and the filtrate is concentrated under reduced pressure to give 9.1 g of ethyl 3-(4-thianyl)propionate as an oily material.
