Reaction Steps
A suspension of 15 g (0.08 mole) of 3-trifluoromethylbenzamide, 16.5 g (0.08 mole) of phosphorus pentachloride and 150 ml of AR carbon tetrachloride was heated at 65°-70° until the HCl gas evolution nearly stops, ca. 30 min. The solution was cooled to 30° and 3.8 g (0.08 mole) of 97% formic acid added dropwise. Stirring was continued for 30 min., then the precipitate was collected, washed with AR carbon tetrachloride and air-dried to give 14 g, m.p. softens 112°, melts 114°-116°.
