By using a procedure similar to that described in Example 22 but starting from β-dimethylaminopropiophenone 2,4,6-triisopropylbenzenesulphonylhydrazone (20 g) and from cyclohexanone (5 cc), 1-(1-hydroxy-1-cyclohexyl)-3-dimethylamino-1-phenyl-1-propene (Z) hydrochloride (6 g) is obtained in the form of a white powder melting at 197° C. after recrystallisation from a mixture (50 cc) of isopropanol and isopropyl ether (60/40 by volume).
