Versuchsvorschrift

To a solution of 4-fluoro-2-methoxy-1-nitrobenzene (2.5 g, 14.60 mmol) in ethanol (25 mL) was added hydrazine hydrate (2.1 g, 43.8 mmol). The reaction mixture was refluxed for 3-4 h. The reaction mixture was concentrated to afford 2.0 g of desired product. 1H NMR (300 MHz, DMSO do): δ 3.84 (s, 3H), 4.46 (s, 2H), 6.31 (d, J=9.3 Hz, 1H), 6.50 (s, 1H), 7.83 (d, J=9.3 Hz, 1H), 8.25 (s, 1H); MS (m/z): (184.01 M)+.
