After stirring for 1.5 hours under ice-cooling, the reaction solution was poured into water and extracted with ether. The ether layer was washed with water and dried over anhydrous magnesium sulfate. The solvent was removed under reduced pressure to obtain 13.1 g of 3-(4-trifluoromethylphenylthio)propionaldehyde.
