with hydrogen;palladium 10% on activated carbon in methanol at 20; under 760.051 Torr; for 18 h;

Steps:

113
Intermediate 113: 2-Amino-4-methoxybenzoic acid4-Methoxy-2-nitrobenzoic acid (3 g, 16.4 mmol) was hydrogenated over palladium on carbon (10%, 300 mg) in methanol (80 mL) at room temperature and normal pressure for 18 hours. The reaction mixture was filtered through celite and concentrated to dryness under reduce pressure to give 2.50 g (100%) of the product as a colorless solid.1H NMR (DMSO-d^ δ 3.70 (s, 3H); 6.09 (dd, IH); 6.23 (d, IH); 7.59 (d, IH).
