Procedure

To a mixture of 2-methyl-6-nitroaniline (106.5 g, 0.7 mol) and NaOAc (63.2 g, 0.77 mol) in acetic acid (525 mL) was added a solution of ICl (125 g, 0.77 mol) in acetic acid (350 mL). The mixture was heated at 80° C. for 50 min and poured into H2O (2100 mL). After stayed at the room temperature for 16 h, the mixture was filtered to furnish yellow solid that was washed with H2O (3×350 mL). Drying under reduced pressure at 40° C. for 48 h afforded the title compound (191 g, 98%). 1H NMR (CDCl3) δ 2.22 (s, 3H), 6.20 (br s, 2H NH), 7.53 (s, 1H), 8.34 (s, 1H). ESI-MS m/z 279 (MH+).
