Reaction Conditions

Reaction Steps

To a solution of 2-(2-naphthyloxy)ethyl 4-bromobenzenesulfonate (Preparation 10, 380 mg, 0.93 mmol) in acetone (5 mL) at room temperature was added sodium iodide (1.0 g, 6.66 mmol). The mixture was heated at 35° C. for 16 hours and then cooled. The residual precipitate was removed by filtration and the filtrate was concentrated in vacuo. The residue was partitioned between diethyl ether (20 mL) and water (20 mL). The two layers were separated and the organic layer was dried over sodium sulfate, filtered, and concentrated in vacuo to give the title compound (200 mg, 72%) as a pale yellow oil.
