Procedure

2,5-Dimethyl-3-nitrobenzoic acid (10.0 g.) was hydrogenated in 200 ml. of methanol in the presence of 0.5 g. of 5% palladium on carbon. The catalyst was removed on a filter and the filtrate was concentrated to dryness to give 8.3 g. of 3-amino-2,4-dimethylbenzoic acid, m.p. 145.5°-146.5° C.
