Procedure: 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.

Procedure: A mixture of 42.0 g of 57% sodium hydroxide dispersed in oil and 700 ml of dimethyl sulfoxide is stirred at 70°-75° for one to one and one-half hours. The solution in diluted with 700 ml of dry tetrahydrofuran and cooled to 0°, under nitrogen. A 200 g of (1.0 mol) sample of trimethylsulfonium iodide is added in portions, maintaining the temperature between 0°-5°. The mixture is stirred for 15 minutes and then a solution of 70.4 g (0.50 mol) of o-chlorobenzaldehyde in 300 ml of dry tetrahydrofuran is added dropwise. The resulting mixture is stirred at room temperature for four hours, poured into water and extracted with ether. The extract is washed with brine, dried and evaporated in vacuo to leave o-chlorostyrene oxide. cooled to 0°, under nitrogen maintaining the temperature between 0°-5° The mixture is stirred for 15 minutes The resulting mixture is stirred at room temperature for four hours extracted with ether The extract is washed with brine dried evaporated in vacuo
