反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: A suspension of 21 g (0.13 mole) of 2,4,6-trimethylbenzamide and 26.8 g (0.13 mole) of phosphorus pentachloride in 200 ml of AR carbon tetrachloride was heated at 70° for 30 min. The solution was cooled to 30° and 6.1 g (0.13 mole) of 97% formic acid added dropwise. Stirred for another 20 min., then filtered, washed with AR carbon tetrachloride and air-dried to give 20.5 g, m.p. 109°-110°. was heated at 70° for 30 min The solution was cooled to 30° filtered washed with AR carbon tetrachloride air-dried to give 20.5 g, m.p. 109°-110°
