Procedure
Cyclobutanol (0.470 mL, 6 mmol) was dissolved in toluene (2 mL) and sodium hydride (60% in mineral oil, 0.240 g, 6 mmol) was added. The reaction was stirred at room temperature for 10 minutes then 2,6-dibromo-pyridine (0.710 g, 3 mmol) was added. The reaction was heated to 110° C. for 16 hours then cooled to room temperature, filtered through Celite, and purified on silica gel (0-5% EtOAc in hexanes) to give the title compound.
