Versuchsvorschrift

First 0.15 g (0.001 mol) of anhydrous tartaric acid and then 0.39 g (0.001 mol) of trans-O-(4-chlorophenylacetyl)-4-(4-dimethylaminomethylphenyl)-cyclohexanol are dissolved in 7 ml of absolute ethanol. Diethyl ether is then added to the clear solution until it becomes slightly cloudy and it is then left to stand for 8 hours at +4° C. The crystalline product precipitated is suction filtered, washed with diethyl ether and dried.
