A solution of 2-fluoro-6-methoxyaniline (1 equiv) in acetic acid (0.7 M) was cooled to 5° C. A mixture of bromine (0.9 equiv) in acetic acid (0.7 M) was slowly added. The reaction mixture was stirred for 2 h at 5° C. The resulting solid was filtered, washed with ether, and dried to give the title compound (90% yield). 1H NMR (500 MHz, DMSO-d6) δ ppm 3.84 (s, 3H) 6.79 (br. s., 2H) 6.97 (s, 1H) 7.06 (d, J=10.09 Hz, 1H). MS (ESI) m/z 219.9 [M+H]+.
