1 g of 1-[1-(2-chloroethyl)-2-cyclohexen-1-yl]-3-methoxybenzene is dissolved in 10 ml of toluene, and the solution is treated with 10 ml of dimethylamine. The mixture is held at 150° C. for 5 hours in a bomb tube. After evaporation of the solvent, the residue is treated with 3 N hydrochloric acid. The aqueous phase is extracted with ether and made alkaline with an excess of ammonia, whereupon the precipitated rac. 1-(m-methoxyphenyl)-N,N-dimethyl-2-cyclohexene-1-ethylamine is taken up in methylene chloride. The hydrochloride of this compound melts at 161°-162° C.
