Procedure

To a solution of 2,6 dichloro-4-iodo pyridine (1 g, 3.65 mmol) in 15 mL tetrahydrofuran was added 1M potassium tert-butoxide (4.02 mL, 4.02 mmol) and the solution heated at reflux for 2 hours. The mixture was diluted with ethyl acetate, washed with water and brine and dried over magnesium sulfate, filtered and concentrated. The crude material was used without further purification. MS (DCI) m/e 312.0 (M+H)+.
