2-BROMO-6-FLUOROPYRIDINE Use and Manufacturing

Into a 50 mL flask equipped with a reflux condenser, 500 mg of the fluorinating agent (1) synthesized in Example 1, 236 mg of 2, 6-dibromopyridine and 2 g of acetonitrile were charged and the resulting mixture was stirred for 3 hours at 80°C. After cooling to room temperature, 5 g of ethyl acetate and 5 g of water were added thereto and stirred. The mixture was separated to two layers by standing. The upper layer was analyzed by gas chromatography (internal standard method) to find that the main product was 2-fluoro-6-bromopyridine. Yield: 78percent (based on 2, 6-dibromopyridine). 2, 6-dibromopyridine was recovered in 20percent.
