β-Dimethylamino-3-methoxypropiophenone 2,4,6-triisopropylbenzenesulphonylhydrazone can be prepared by a method similar to that described in Example 22 for the preparation of β-dimethylaminopropiophenone 2,4,6-triisopropylbenzenesulphonylhydrazone, but starting from 2,4,6-triisopropylbenzenesulphonylhydrazine (25.3 g) and β-dimethylamino-3-methoxypropiophenone hydrochloride (20.7 g). In this way β-dimethylamino-3-methoxypropiophenone 2,4,6-triisopropylbenzenesulphonylhydrazone hydrochloride (26.1 g) is obtained in the form of a white solid melting at 188° C.
