Procedure

Shake 85 g. of 2'-nitro-4'-trifluoromethylisobutyranilide in 1.0 liter of ethanol containing 3.0 g. of 5% palladium on charcoal in a parr shaker under approximately 50 lbs. per square inch hydrogen pressure for twenty-four hours. Filter, remove the ethanol and recrystallize from a dichloromethane-chloroform-hexane mixture, obtaining the product of this step.
