Vorschrift

A solution of 0.39 g (0.001 mol) of trans-O-(4-chlorophenylacetyl)-4-(4-dimethylaminomethylphenyl)-cyclohexanol in 10 ml of diethyl ether is combined at ambient temperature, with stirring, with a 1.5 times equimolar amount of hydrogen chloride in isopropanol added dropwise. The precipitate formed is left for 1 hour at ambient temperature, suction filtered, washed repeatedly with diethyl ether and dried. White crystals are obtained, melting point 231°-233° C.
