Procedure

Heat a solution of 2-(4-methanesulfonyl-phenyl)-6-methoxy-1-(4-nitro-phenoxy)-naphthalene (1.67 g, 3.7 mmol), ammonium formate (4.7 g, 74 mmol), wet 20% palladium hydroxide on carbon (420 mg, 25 wt %) and absolute ethanol (80 mL) at reflux for 1 hour, then cool to ambient temperature, filter and evaporate to dryness under reduced pressure. Partition the residue with dichloromethane/water. Dry the organic layer with solid magnesium sulfate and chromatograph on silica gel with dichloromethane/methanol mixtures to give 1.15 g of 4-[2-(4-methanesulfonyl-phenyl)-6-methoxy-naphthalen-1-yloxy]-phenylamine (75%).
