By using a method similar to that described in Example 22, but starting from β-dimethylaminopropiophenone 2,4,6-triisopropylbenzenesulphonylhydrazone (20 g) and from o-tolualdehyde (5.78 g), 4-dimethylamino-1-(2-methylphenyl)-2-phenyl-2-buten-1-ol (Z) hydrochloride (10.2 g) is obtained in the form of a white powder melting at 204° C. after recrystallisation from ethanol (100 cc).
