The reaction solution was concentrated under reduced pressure. Ice cooled 1N hydrochloric acid (40 ml) and ethyl acetate (200 ml) were added to the residue and separated to two layer. The organic layer was washed with aqueous saturated sodium chloride solution (40 ml) twice, dried over anhydrous magnesium sulfate, filtered off inorganic salt and concentrated under reduced pressure to obtain N-(3-methylphenyl)-3-(phenylthio)acrylamide (3.46 g).
