Reaction Steps
A mixture of 3-fluoro-4-nitrophenol (2.20 g, 14.0 mmol) in 25 mL ethyl acetate is evacuated under reduced pressure and filled with nitrogen three times. Palladium, 10% by weight on carbon (220 mg) is added. The mixture is evacuated under reduced pressure and filled with nitrogen three times. The mixture is evacuated under reduced pressure and filled with hydrogen. The mixture is stirred under hydrogen atmosphere (balloon) over night. The mixture is then filtered over diatomaceous earth and concentrated to provide the title compound (1.7 g, 96%) as a brown solid. 1H NMR (400 MHz, DMF-d7) δ 8.75 (s, 1H), 6.78 (m, 1H), 6.40 (m, 1H), 6.50 (m, 1H), 4.38 (s, 2H).
