Procedure
A suspension of 18.1 g (0.12 mole) of 4-cyanobenzamide, 25.8 g (0.12 mole) of phosphorus pentachloride and 250 ml of AR carbon tetrachloride was stirred and heated at 70° until the HCl gas evolution had subsided; ca. 25 min. The solution was cooled to 30° and 5.9 g (0.12 mole) of 97% formic acid was added while maintaining a temperature of 30°. After stirring for 30 min., the product was collected, washed with AR carbon tetrachloride and dried to give 52 g, m.p. shrinks 162°-165°, darkens 218°, decomposes >300°.
