Procedure

p-Toluidine (2.46 g) was dissolved to acetonitrile (20 ml), then acetonitrile (3 ml) solution of 3-(phenylthio)acryloyl chloride (2.0 g) was added dropwise thereto under ice-cooling. The mixture was stirred at room temperature for 1.5 hours. The reaction mixture was poured into 50 ml of ice-water, and adjusted to pH 4 with concentrated hydrochloric acid. The precipitated crystal was collected by filtration, washed with water and dried to obtain N-(4-methylphenyl)-3-(phenylthio)acrylamide (2.62 g) as light brown crystal.
