A mixture of 3-nitro-5-(2-oxopyrrolidin-1-yl)-benzoic acid (D5) (2.86 g) and 10% Pd—C (0.7 g) in methanol (450 ml) water (50 ml) was hydrogenated at atmospheric pressure for 3 hrs. The mixture was filtered through Celite and concentrated to give 3-amino-5-(2-oxopyrrolidin-1-yl)-benzoic acid (2.70 g).
