By using a method similar to that described in Example 22, but starting from β-diethylaminopropiophenone 2,4,6-triisopropylbenzenesulphonylhydrazone (30 g) and benzaldehyde (6.9 cc), 4-diethylamino-1,2-diphenyl-2-buten-1-ol (Z) hydrochloride (3.2 g) is obtained, after recrystallisation from acetone, in the form of white crystals melting at 140° C.
