Reaction Steps
To a solution of 1,2,3-trimethoxy-5-nitrobenzene (6.64 g, 31.2 mmol) in ethanol (250 mL) was added palladium on carbon (10%, 300 mg) and hydrazine hydrate (85%, 5.7 mL). After emission of gas has ceased, the reaction mixture was heated at refluxed for 1 hour, cooling to room temperature, filtered and evaporated to afford the product 3,4,5-trimethoxyaniline as a white solid (5.5 g, yield 96.4%). 1H NMR (400 MHz, DMSO-d6) δ ppm 5.86 (s, 2H), 4.82 (br, 2H), 3.64 (s, 6H), 3.50 (s, 3H).
