A solution of 4'-nitrovaleranilide (13.33 g., 0.06 mole) in absolute ethanol (750 ml.) is hydrogenated over 10% palladium on charcoal (2 g.) until the theoretical absorption is achieved. The catalyst is removed and the solvent is removed in vacuo. The residue is recrystallized from butyl chloride to yield 9.0 g., m.p. 81°-83° C.
