Reaktionsschritte

A solution of 2-chloro-4-fluoro-5-nitrotoluene (30.0 g, 0.158 mole) in glacial acetic acid (150 ml) was added to a 250 ml Parr bottle which contained platinum IV oxide (0.4 g). The Parr bottle was placed on a Parr hydrogenation apparatus and charged with hydrogen. The reaction mixture was allowed to shake until hydrogen absorption ceased. The catalyst was removed by vacuum filtration. The filtrate containing 4-chloro-2-fluoro-5-methylaniline was used in the following step. This reaction was repeated several times.
