Reaktionsschritte

A mixture containing 21.3 g (0.1 mole) of 3-phenoxybenzamide, 20.8 g (0.1 mole) of phosphorus pentachloride and 250 ml of Ar carbon tetrachloride was heated at 70° for 30 min. The resulting solution was cooled to 30° and 4.7 g (0.1 mole) of 97% formic acid added dropwise. Stirring was continued for 20 min., the reaction was filtered, washed with AR carbon tetrachloride and air-dried to give 31 g, m.p. 122°-125°.
