Reaction Steps
A suspension of 29 g (0.19 mole) of 2,4-dimethylbenzamide, 40.5 g (0.19 mole) of phosphorus pentachloride and 300 ml of AR carbon tetrachloride was heated at 70° for 30 min. The solution was cooled to 30° and 9.2 g (0.19 mole) of 97% formic acid added dropwise. Stirring was continued for another 20 min., then the product was collected by filtration, washed with AR carbon tetrachloride and air-dried to give 30.5 g, m.p. decomposes upon standing.
