Reaction Steps
To a solution of 4-(pyridin-3-yl)-2-nitroaniline (1.3 g, 9 mmol) in HOAc (25 mL) was added bromine (1.58 g, 9.9 mmol) in HOAc (5 mL). The resulting mixture was stirred at room temperature for one hour and then quenched with ice-water. The solids were collected, washed with water and dried. The solids in EtOAc was then washed with NaOH (2N; 20 mL), water, brine and concentrated in vacuo. The concentrate was purified by chromatography [Silica Gel, ethyl acetate: hexanes (1:1)] to afford the title compound (0.8 g). 1H NMR (CDCl3) δ 8.83 (d, 1H), 8.55 (m, 1H), 8.41 (d, 1H), 8.15 (d, 1H), 7.96 (m, 1H), 7.41 (m, 1H), 6.80 (br s, 2H). (M+1) 294.
