실험 절차
1.0 g of 1-(m-methoxyphenyl)-2-cyclohexene-1-acetaldehyde is dissolved in 10 ml of methanol, and after treatment with 10 ml of methylamine, the mixture is stirred at room temperature overnight with a magnetic stirrer in a bomb tube. After evaporation of the solvent, the residue is dissolved in ethanol. Then, the solution is treated with 0.5 g of sodium borohydride, stirred at room temperature for 2 hours. The solvent is removed by evaporation, and the residue is taken up with 3 N hydrochloric acid. The aqueous phase is extracted with ether and made alkaline by the addition of concentrated ammonia, whereupon the resulting rac. 1-(m-methoxyphenyl)-N-methyl-2-cyclohexene-1-ethylamine is taken up in methylene chloride. The hydrochloride of this compound melts at 177°-179° C.
