By using a method similar to that described in Example 22, but starting from β-dimethylaminopropiophenone 2,4,6-triisopropylbenzenesulphonylhydrazone (20 g) and 3-bromobenzaldehyde (5.6 cc), 1-(3-bromophenyl)-4-dimethylamino-2-phenyl-2-buten-1-ol (Z) hydrochloride (11.3 g) is obtained in the form of a white solid melting at 188° C. after recrystallisation from isopropanol (200 cc).
