A solution of 13.29 gm. (0.04 mole) of 3,3',5-trinitrobenzanilide in 150 ml. of dioxane is hydrogenated at three atmospheres of hydrogen using 1 gm. of 10% palladium-on-charcoal catalyst. The catalyst is removed by filtration, the filtrate evaporated to dryness under reduced pressure, and the residue dried by distilling 200 ml. of benzene from the reaction mixture.
