Versuchsvorschrift

To a solution of Raney nickel (50 g) in ethanol (100 ml) is added a solution of 2,4-difluoro-3-methyl-6-methylthiomethylaniline (4.79 g) in ethanol (30 ml) at room temperature with stirring, followed by stirring at room temperature for 30 minutes. The Raney nickel is filtered off and the filtrate is diluted with water, extracted with dichloromethane, and the extract is washed with water and dried. The solvent is distilled off under reduced pressure to give 2,4-difluoro-3,6-dimethylaniline (3.14 g).
