Versuchsvorschrift

A mixture of 5.25 g of N-tert-butyl-2-nitro-4-trifluoromethylaniline, 20 ml of ethyl acetate and 5% palladium charcoal was stirred for 9 hours at room temperature under a hydrogen atmosphere of about 1 atm. The reaction mixture was filtrated through Celite (registered trademark). The filtrate was washed with water, dried over sodium sulfate, then, concentrated under reduced pressure to obtain a residue. The resultant residue was subjected to silica gel chromatography to obtain 4.82 g of N1-tert-butyl-4-trifluoromethylbenzene-1,2-diamine.
