A solution of 2-dimethylamino-5-nitro-benzoic acid (200 mg, 0.95 mmol) in methanol (15 ml) was hydrogenated over 10% Pd/C (20 mg) at 30 psi until no further gas uptake was observed. The reaction mixture was then filtered over celite and the filtrate evaporated to yield the crude product. Recrystallisation using pet. ether yielded 5-amino-2-dimethylamino-benzoic acid (110 mg, 70%).
