The mixture was stirred at 20° C. for 12 h. LCMS showed the reaction was finished. The mixture was extracted with EA, washed with water, and concentrated to give 3-nitro-5-(trifluoromethyl)benzamide (1.5 g, 5.86 mmol, 83% yield): 1H NMR (400 MHz, DMSO-d6) δ 8.91 (s, 1H), 8.62 (br.s, 2H), 8.53 (s, 1H), 7.93 (s., 1H). ES-LCMS m/z 235 (M+H).
