Reaction Steps

10% Palladium on activated carbon (0.22 g, 2.06 mmol, 0.48 eq) is added at room temperature to a stirred solution of (3,4-dimethoxy-2-nitro-phenylamino)-acetic acid (1.1 g, 4.29 mmol, 1.0 eq) in methanol (30 mL). The mixture is hydrogenated for 16 hours, then filtered through decalite. Solvent is removed to afford 7,8-dimethoxy-3,4-dihydro-1H-quinoxalin-2-one as an off-white solid (0.46 g, 52% yield).
