실험 절차

5-Bromo-2-(2-nitrovinylamino)benzoic acid (Compound A, 87 mmol) and potassium acetate (104 mmol) in acetic anhydride (1185 mmol) were stirred for 3 h at 120° C. The precipitate was filtered, and washed with acetic acid till the filtrate was colorless. It was further washed with water and dried to obtain the title compound. 1H NMR (CDCl3, 500 MHz): δ 9.275 (s, 1H), 8.611-8.615 (d, 1H, J=2 Hz), 8.100-8.118 (d, 1H, J=9 Hz), 8.026-8.048 (dd, 1H, J=8.5 Hz, 2 Hz).
