Reaction Steps

To a suspension of 68 g (0.41 mole) of 4-nitrobenzamide in 400 ml of AR carbon tetrachloride at 48° was added portionwise 85.2 g (0.41 mole) of phosphorus pentachloride. The reaction was heated at 65°-70° for 50 min., then cooled to 25°-30°. Added dropwise while maintaining a temperature of 30°, 19.4 g (0.41 mole) of 97% formic acid. After the evolution of gas (CO and HCl) had ceased the reaction was filtered, washed with AR carbon tetrachloride and air-dried to give 103.2 g, m.p. 134°-135.5°.
