Versuchsvorschrift
82.2 g of 6A was dissolved in 300 ml of ethanol. 0.5 g of platinum oxide catalyst was added and the mixture was hydrogenated at 50 psig. Fresh portions of catalyst were added periodically. The reaction mixture was filtered, and the filtrate was concentrated. The residue was crystallized from water to give 2-amino-4-(trifluoromethyl)phenol (6B).
