Reaction Conditions

Reaction Steps

To a solution of 2,6-difluoroaniline (1.0 g, 7.75 mmol) in 11.1 mL of acetic acid and 1.69 mL of concentrated hydrochloride solution, sodium nitrite (600 mg, 9.3 mmol) in 2.7 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 (1.78 g, 21.7 mmol) and acetylacetone (1 g, 10 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 (400 mg, 21% yield): 1H NMR (400 MHz, CDCl3): δ ppm 2.43 (s, 3H), 2.61 (s, 3H), 6.97-7.03 (m, 2H), 7.05-7.15 (m, 1H), 14.42 (s, 1H).
