Versuchsvorschrift

The synthesis was carried out according to the procedure of Example 1, except that 5.0 g (0.028 mole) of 2,5-dichlorobenzaldehyde were used instead of 3-methoxybenzaldehyde. The reaction steps involving Grignard reaction, oxidation and Mannich reaction led to a total yield of 1.4 g (14%) of (2RS)-2-benzyl-1-(2,4-dichlorophenyl)-3-dimethylaminopropan-1-one hydrochloride with a melting point of 140° C.
