A solution of 7.9 g. of 4-acetylamino-3,5-bis-trifluoromethylnitrobenzene in 200 ml. of ethanol is hydrogenated under 40 lbs. of hydrogen pressure with 1 g. of 5% palladium on charcoal catalyst. When the calculated amount of hydrogen is consumed, the solution is filtered and concentrated in vacuo to give 4-acetylamino-3,5-bis-trifluoromethylaniline.
