Reaction Steps

To an ice-cold solution of 2-amino-5-nitro phenol (40.0 g, 259.52 mmol) in DCM (1.0 L), was added bromine (13.38 mL, 259.52 mmol) drop wise. The resulting reaction mixture was stirred at room temperature for 45 min. After the completion of the reaction (TLC monitoring), water was added and extracted with EtOAc (3×1.0 L). The combined organics was dried over anhydrous Na2SO4 and concentrated under reduced pressure. The crude (55.0 g, 92%) was carried forward to the next step without further purification.
