Reaction Steps

A suspension of 47 g (0.31 mole) of 4-methoxybenzamide, 64.7 g (0.31 mole) of phosphorus pentachloride and 500 ml of AR carbon tetrachloride was heated at 60°-70° for 45 min. by which time the HCl evolution had nearly stopped. Cooled to room temperature where 14.8 g (0.31 mole) of 97% formic acid was added dropwise. The reaction was stirred for an additional 30 min., then filtered, washed with AR carbon tetrachloride and air-dried to give 73.4 g, m.p. 92°-93°.
