Reaction Steps
To a solution of 6-chloro-3-fluoropyridin-2-carboxylic acid (250 mg) in methanol (3 ml), 0.3 ml of concentrated sulfuric acid was added, and the reaction solution was heated to reflux for 2.5 hours. The reaction solution was cooled, and then the solvent was distilled off under reduced pressure. To the residue obtained was added 1N aqueous sodium hydroxide, and the mixture was extracted with ethyl acetate. The combined organic layers were washed with a saturated saline solution and dried over anhydrous sodium sulfate. The solvent was distilled off under reduced pressure to afford the title compound as a white solid.
