6-Bromo-4-fluoro-2,3-dinitrophenol (4.4 g, 16 mmol) was stirred in methanol (88 mL) and 12.0 M hydrogen chloride in water (40 mL), followed by addition of stannous chloride dihydrate (11 g, 47 mmol) and the mixture was stirred at room temperature for 15 min. The mixture was diluted with water and extracted with ethyl acetate. The organic layer was separated and concentrated. Purification on silica gel eluting ethyl acetate in hexanes gave the amine product.
