The problem of the N-demethylation of quaternary ~onium salts has bee a perennial one in organic chemistry. The classical method for demethylatio Involves the pyrolysis of ammonium halides, which may however lead to extens deoomposition. 2 Refluxing ethanolamine has also been used for purpqeee of

Several good methods are known for the monodealkylation of quaternary ammonium compounds employing non-reductive nucleophilic agents (l-5). We wish to report here a simple one-step method that leads directly from a quaternary ammonium salt to the acyl derivative of the corresponding secondary amine
