To an ethanol solution (300 ml) of 2-fluoro-4-bromo-5-methoxycarbonyloxy nitrobenzene (30.4 g, 0.1 mol) was added platinum dioxide (1.0 g) and the mixture was stirred under a hydrogen atmosphere until no hydrogen was absorbed. After the removal of the catalyst by filtration, the solvent of the filtrate was evaporated under reduced pressure to give a brown solid (28.0 g) of 2-fluoro-4-bromo-5-methoxycarbonyloxy aniline.
