Heated at 70° for 25 min. at which time the HCl gas evolution had ceased, a mixture of 59 g (0.4 mole) of cinnamide, 83.5 g (0.4 mole) of phosphorus pentachloride and 500 ml of AR carbon tetrachloride. After cooling to 30°, added dropwise, 19 g (0.4 mole) of 97% formic acid. Chilled to 0° and filtered. Air-dried to give 107.5 g, m.p. softens 82°, melts 83°-90°.
