Procedure

A mixture of 1.38 g of 4-(pentafluoroethyl)-2-nitrophenol, 15 ml of ethyl acetate and 0.15 g of 5% palladium on carbon was stirred under about one atmosphere of hydrogen at room temperature for four hours. The reaction mixture was filtered through Celite™. The filtrate was concentrated under reduced pressure. The residue was washed with hexane to give 1.02 g of 2-amino-4-(pentafluoroethyl)phenol.
