実験手順
Following the general procedure I, 0.25 mol of 4,5-dichloro-2-methylaniline in 200 ml of water and 60 ml of concentrated hydrochloric acid are hydrogenated in the presence of the catalyst from Example 1 at 220° C. over the course of 30 minutes under a hydrogen pressure of 100 atmospheres gauge. 5-Chloro-2-methylaniline is obtained in a yield of 82% and a purity of 99%.
