Versuchsvorschrift

2-Methyl-3-nitrobenzoic acid (5 g) is dissolved in ethanol (50 ml) and the mixture is subjected to catalytic reduction with 5% palladium carbon (0.25 g) at room temperature for 5 hours. The catalyst is removed by filtration, and the filtrate is concentrated to give 3-amino-2-methylbenzoic acid (4.4 g).
