By using a method similar to that described in Example 22 but starting from β-dimethylaminopropiophenone 2,4,6-triisopropylbenzenesulphonylhydrazone (20 g) and from α-tetralone (6.4 cc), 1-(1-hydroxy-1,2,3,4-tetrahydro-1-naphthyl)-3-dimethylamino-1-phenyl-1-propene (Z) (3.8 g) is obtained in the form of a white powder melting at 108° C. after recrystallisation from a mixture (65 cc of petroleum ether and isopropanol (95/5 by volume).
