Versuchsvorschrift

NaOAc (17.6 g) and Br2 (6.76 mL) was added to a solution of 2-methoxy-6-nitrobenzenamine (21.74 g) in HOAc (250 mL). The mixture was stirred at room temperature for 20 min. The resulting precipitate was filtered, washed with water and dried in-vacuo to afford the desired product as a yellow solid (26.43 g, 83%). 1H NMR (300 MHz, DMSO-d6) δ 3.91 (s, 3H), 7.18 (d, 1H, J=1.8 Hz), 7.70 (d, 1H, J=1.8 Hz); LC-MS: m/e=247 [M+1]+
