実験手順
3-Chloro-2-nitroaniline (5.00 g, 29.0 mmol) was dissolved in glacial acetic acid (258 mL). N-Bromosuccinimide (5.06 g, 28.4 mmol) was added and the resulting mixture was refluxed for 1 hour. The reaction was cooled to room temperature and poured into water to give a precipitate that was filtered, rinsed with water and dried to constant weight to give the title compound (4.78 g, 67%). 1H NMR (400 MHz, CDCL3) δ ppm 7.46 (d, J=9.0, 1H), 6.64 (d, J=9.0, 1H), 4.74 (s, 2H).
