Reaction Steps
The crude 2-nitro-4-ethylaniline was hydrogenated in 100 ml. of ethanol over 500 mg. of 5 percent palladium on charcoal, until gas uptake ceased. The reaction mixture was filtered and evaporated, yielding 4-ethyl-o-phenylenediamine as a dark oil which solidified overnight. The identity of the product was confirmed by IR.
