Procedure

A solution of 14.3 g. of 3,3'-dinitrobenzanilide in 150 ml. of dioxane is hydrogenated at three atmospheres of hydrogen using 1 g. of 10% palladium-on-charcoal catalyst. The catalyst is removed by filtration and the filtrate evaporated to dryness. The residue is recrystallized from ethanol. There is obtained 8.72 g. of material melting at 123°-4°.
