Reaction Steps

((b) Ethyl alcohol (100 mL) was added to a flask containing 3-nitro-4-methylaminobenzoic acid (2.09 g, 10.7 mmol) and 10% Pd/C (30 mg) under a steady stream of N2. The mixture was stirred under hydrogen for 16 hours, filtered through a milipore 0.22 μm type GV filter disc and concentrated on a rotary evaporator. The residue was dried under vaccum to provide 3-amino-4-methylaminobenzoic acid (1.1 g, 61% yield).
