Procedure

To a solution of 1-methyl-4-nitro-naphthyl-amine (4.0 g, 21 mmol) in ethanol (300 mL) was added Raney-Nickel (4 scoops). The mixture was stirred under H2 (1 atm) for 16 h. The reaction was filtered through a pad of Celite and concentrated. Purification by silica gel flash column chromatography (EtOAc:Hexanes=15:85) provided product (3.2 g, 75%).
