Hydrochloric Acid → N-Carboxymethylimidazoline Hydrochloride

Participants

Reaction Steps

A suspension of 10.9 g. (0.05 mole) of N-carbobenzyloxymethylimidazoline and 50 mg. of 5% palladium-on-charcoal in 100 ml. of ethanol is shaken in an atmosphere of hydrogen at atmospheric pressure. When the theoretical amount of hydrogen has been absorbed, the spent catalyst is filtered and the filtrate treated with one equivalent of hydrogen chloride dissolved in ethyl acetate. The resulting solution is then concentrated to dryness in vacuo and the residual product triturated with ether and filtered.
