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-anisaldehyde (6.5 g), 4-dimethylamino-1-(2-methoxyphenyl)-2-phenyl-2-buten-1-ol (Z) (7.2 g) is obtained in the form of a white powder melting at 77° C. after recrystallisation from a mixture (85 cc) of petroleum ether and isopropyl ether (70/30 by volume).
