Participants

Reaction Steps

Combine anthranilonitrile (2.36 g, 20 mmol), sodium hydride (1.2 g (60% in oil), 30 mmol) and THF (50 mL), stir at ambient temperature for 30 minutes. Add 1-bromo4-chloro-2-nitro-benzene (7.1 g, 30 mmol) and stir at ambient temperature for 3 days. Pour the reaction mixture in ice-cold concentrated hydrochloric acid (200 mL) and filter the resulting solid. Purify by flash chromatography (dichloromethane) and recrystallize from hot ethyl acetate to give (1.62 g, 30%) of the title compound as orange needles: 1H NMR (CDCl3) δ 7.17 (d, 1H), 7.26 (t, 1H), 7.40–7.51 (m, 2H), 7.61 (t, 1H), 7.72 (d, 1H), 8.22 (d, 1H), 9.54 (bs, 1H).
