The preparation of 2-[N-(ethyl)-(N-beta-hydroxyethyl)]amino-ethyl 2,2-diphenylpropionate (1), a metabolite of aprophen [2-diethylaminoethyl 2,2-diphenylpropionate], is described. Hydrolysis of [2-(2-chloroethyl)ethylamino]ethyl acetate hydrochloride (2) in a basic solution, followed by acidic pH adjustment, gave the ethylcholineaziridinium ion (3) that upon treatment with 2,2-diphenylpropionic acid
