A mixture of 4,5-dichloro-2-nitro-phenylamine (0.500 g, 2.42 mmol), N-chlorosuccinimide (0.403 g, 3.02 mmol), and DMF (5 mL) was heated to 100° C. for 1 h. After cooling to 23° C., the solution was poured into ice water. The yellow precipitate was collected by filtration and dissolved in dichloromethane. The organic phase was washed with water, dried (MgSO4), filtered, and concentrated to yield the titled compound (0.468 g, 81%). 1H NMR (400 MHz, CDCl3): 8.28 (s, 1H), 6.70 (s, 2H). The compound did not yield MS data.
