By using a method similar to that described in Example 22, but starting from β-(1-pyrrolidinyl)propiophenone 2,4,6-triisopropylbenzenesulphonylhydrazone (20 g), and benzaldehyde (4.6 cc), 1,2-diphenyl-4-(1-pyrrolidinyl)-2-buten-1-ol (Z) hydrochloride (9.9 g) is obtained, after recrystallisation from a mixture of 2-propanol and isopropyl ether (40/60 by volume), in the form of white crystals melting at 106° C.
