Reaction Steps

To a solution of 2-fluoro-3-(trifluoromethyl)aniline (1.0 g, 5.58 mmol) in 8 mL of acetic acid and 1.3 mL of concentrated hydrochloride solution, sodium nitrite (462 mg, 6.69 mmol) in 2.1 mL of water was added dropwise at 0° C., and the mixture was stirred at 0° C. for 1 h. Then to the reaction mixture were added sodium acetate (1.37 g, 16.8 mmol) and acetylacetone (726 mg, 7.26 mmol). The mixture was stirred at room temperature for 2 h, filtered, washed with water, EtOH/H2O (1/1) and hexane, and dried to give the title compound (900 mg, 55% yield). 1H NMR (400 MHz, CDCl3): δ ppm 2.51 (s, 3H), 2.63 (s, 3H), 7.30-7.34 (m, 1H), 7.38-7.41 (m, 1H), 7.94-7.96 (m, 1H), 14.66 (s, 1H).
