Versuchsvorschrift

To a solution of 4-(2-hydroxy-ethylamino)-3-nitro-benzoic acid methyl ester (3.0 g, 12.4 mmol) in methanol was added 10% Pd/C (800 mg). The mixture was hydrogenated at 1 atmospheric pressure for 2 h. The catalyst was filtered off and the methanol evaporated to give 2.6 g (99%) of 3-amino-4-(2-hydroxyethylamino)-benzoic acid methyl ester.
