Procedure

To a pressure reaction bottle was added 10 g 2-nitrodiphenylamine, 0.5 g 5% palladium on carbon and 100 ml 95% ethanol. The mixture was hydrogenated at 22 C and 40 psi hydrogen for 2 hours. Following filtration through celite and solvent removal, an oil was obtained that crystallized on standing.
