A 1 L round bottom flask equipped with a stir bar and reflux condenser was charged 5H2SO4 (4 mL), methanol (400 mL) and 3-fluoro-4-nitrobenzoic acid (10 g). The reaction mixture was heated at reflux temperatures with vigorous stirring for 18 h. The methanol was removed and the crude residue was triturated with hexane and concentrated to give a colorless solid (9.79 g) that was used without further purification.
