2-Bromo-6-nitroaniline A mixture of 1-bromo-2-fluoro-3-nitrobenzene (6.0 g, 27.27 mmol) and NH3 in CH3OH (7 M, 20 mL) was stirred in a sealed tube at 100 °C for 16 h. The solvent was removed and the residue was dissolved in H2O, and then extracted with ethyl acetate. The organic layer was washed with brine, dried over Na2SO4 and concentrated. The residue was purified by column chromatography on silica gel (ethyl acetate/petroleum ether = 1:100) to afford the product as a yellow solid (5.4 g, 91.3% yield).
