Procedure
To a solution of 6-chloropyridin-2-ol (3.00 g, 23.2 mmol) and sodium carbonate (4.88 g, 46.4 mmol) in water (60 mL) was added iodine (5.84 g, 23.0 mmol), and the mixture was stirred at room temperature overnight. The resulting solid was collected by filtration, 1N hydrochloric acid was added to the obtained solid, and the mixture was extracted twice with ethyl acetate. The extract was washed with saturated brine, and dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure, and to the obtained residue were added diisopropyl ether and hexane, and the resulting solid was collected by filtration to give the title compound (1.04 g, yield 18%).
