Procedure
A mixture of 75 g (0.42 mole) of 4-tert-butylbenzamide, 88.1 g (0.42 mole) of phosphorus pentachloride and 750 ml of AR carbon tetrachloride was heated at 70° until the evolution of HCl had nearly ceased. The reaction was cooled to 30° and 19.5 g (0.42 mole) of 97% formic acid, added dropwise. After the 20 min. addition, it was chilled to 0°, filtered, washed with AR carbon tetrachloride and air-dired to give 82 g, m.p. 110°-111°.
