Procedure

A mixture of 3-(2-naphthyl)-1-nitrobenzene (5.4 g), iron (3.63 g) and acetic acid (13.0 g) in ethanol (50 ml) was stirred under reflux for 3 hours. The reaction mixture was diluted with chloroform, filtered and treated with saturated sodium bicarbonate solution. The chloroform layer was separated, dried, evaporated and chromatographed on silica gel to give 3-(2-naphthyl)aniline (5.2 g).
