2-Fluoro-4-(1,1,2,2-tetrafluoroethoxy)nitrobenzene → 2-Fluoro-4-(1,1,2,2-tetrafluoroethoxy)aniline

0.20 Gram of 2-fluoro-4-(1,1,2,2-tetrafluoroethoxy)nitrobenzene, 0.03 g of platinum dioxide and 5 ml of ethyl acetate were added to a reactor, and the atmosphere in the reactor was replaced by a hydrogen stream with stirring. Stirring was then continued at room temperature for 2 hours while introducing a hydrogen gas. Thereater, the reaction solution was filtered off, and the filtrate was concentrated to obtain 0.15 g of 2-fluoro-4-(1,1,2,2-tetrafluoroethoxy)aniline.
