To a solution of 4-bromo-2-methoxy-6-nitrobenzenamine (27.85 g) in HOAc (150 mL) and Ac2O (17 mL) was added conc. H2SO4 at 70° C. and the mixture was stirred at 70° C. for 30 min and kept at rt overnight. The formed precipitate was collected by filtration and washed with hexane to afford the desired product as a light yellow solid (24.45 g, 75%). 1H NMR (300 MHz, DMSO-d6) δ ppm 2.01 (s, 3H), 3.92 (s, 3H), 7.61 (d, 1H, J=1.8 Hz), 7.65 (d, 1H, J=1.8 Hz), 9.91 (s, 1H); LC-MS: m/e=289 [M+1]+
