Procedure

A mixture of triiodophenol (5.78 g, 12.3 mmol) and sodium hydride (0.49 g, 60% dispersion, 12.3 mmol) in DMF (15 ml) was stirred at room temperature for 1 hour and then a solution of 1,3-bis-(methanesulfonyloxy) butane (1.37 g, 5.58 mmol) in DMF (5 ml) was added. The mixture was heated to 90° C. for 6 hours and then poured into water after cooling. Ethyl acetate was added and the mixture was allowed to stand overnight. The precipitated solid was collected and dried to give 3.0 g (54%) of the desired product, Mp 173°-175° C.
