Similarly 2.71 g. (0.01 mol) of N-benzyl-3,4-dimethoxyphenethylamine and 2.33 g. (0.015 mol) of o-chlorostyrene oxide are reacted in methanol to give N-benzyl-N-[2-(3,4-dimethoxyphenyl)ethyl]-2-hydroxy-2-(2-chlorophenyl)ethylamine. The latter is converted to its hydrochloride, which is dissolved in 90 ml. of methanol and hydrogenated over 1 g. of 10% palladium-on-carbon in 10 ml. of ethyl acetate at room temperature for six hours. The reaction mixture is filtered and evaporated in vacuo to leave N-[2-(3,4-dimethoxyphenyl)ethyl]-2-hydroxy-2-(2-chlorophenyl)ethylamine hydrochloride, m.p. 128°-132° C.
