Reaction Steps
A suspension of 68 g, (0.44 mole) of 4-chlorobenzamide, 91 g (0.44 mole) of phosphorus pentachloride and 700 ml of AR carbon tetrachloride was heated at 65°-70° for 25 min. The solution was cooled to 20° and 20.7 g (0.44 mole) of 97% formic acid added dropwise. After the HCl gas evolution had nearly stopped, ca. 30 min., the precipitate was collected by filtration, washed with AR carbon tetrachloride and air-dried to give 103 g, m.p. 114.5°-115.5°.
