Procedure

Place 6-methoxy-2-(4-methanesulfonylphenyl)-1-(4-aminophenoxy)naphthalene hydrochloride (1 eq.), iodine (0.6 eq.), copper iodide (1.05 eq.) and acetonitrile in a 3 neck flask equipped with a mechanical stirrer, addition funnel, nitrogen purge and temperature probe. Charge the addition funnel with isoamylnitrite (1.1 eq.) in acetonitrile and add this mixture dropwise at 20° C. or below. After the addition, stir the mixture for 1 hour. Once the reaction is complete, add saturated sodium thiosulfate and methylene chloride to the mixture and stir for 1 hour. Filter the reaction mixture and separate the layers. Concentrate the organic layer to form a solid. Purify the solid on silica gel to afford the title compound.
