Procedure

A mixture of 23.5 g (0.12 mole) of 4-phenylbenzamide, 24.8 g (0.12 mole) of phosphorus pentachloride and 250 ml of AR carbon tetrachloride was heated at 70° until the HCl gas evolution nearly stops. It was chilled to 30° and 5.7 g (0.12 mole) of 97% formic acid added dropwise. The precipitate was collected, washed with AR carbon tetrachloride and air-dried to give 3.1 g, m.p. 123°-124°.
