Reaction Steps

To a solution of 2-nitro-phenylamine (13.8 g, 100 mmol) in HOAc (150 mL) was added NBS (18 g, 101 mmol). The reaction mixture was stirred and heated to reflux over 1 hour. The cooled reaction mixture was poured into H2O (1000 mL) and stirred for 15 minutes. The resulting orange slurry was filtered and washed with H2O (300 mL) affording a 20.26 g (93%) of the title compound as a bright orange solid.
