Hydrochloric Acid → Benzamide

Participants

Reaction Steps

A solution of 4.1 g of 5-chloro-2-methoxy-benzoyl chloride in 20 ml of toluene was added dropwise to a suspension of 4.65 g of 2-(4-ethylphenyl)-ethylamine hydrochloride in 100 ml of anhydrous toluene after addition of 5 ml of pyridine. The whole was heated under reflux, then shaken with water, dilute hydrochloric acid and a solution of sodium bicarbonate and dried over sodium sulfate. After concentration under reduced pressure, the residue, which solidified only slowly, was filtered off with suction after addition of petroleum ether (B.p. 30°-60° C.). The 5-chloro-2-methoxy-N-(2-<4-ethylphenyl>-ethyl)-benzamide so obtained was found to melt at 66°-68° C.
