Reaction Steps
A 5M potassium hydroxide aqueous solution (2 ml) was added to a THF/MeOH (2 ml/2 ml) solution containing methyl 5-fluoro-6-(2H-1,2,3-triazol-2-yl)nicotinate (250 mg), followed by stirring at room temperature for 1 hour. 6M hydrochloric acid was added to the reaction solution so as to acidify the reaction solution, followed by extraction with ethyl acetate. The organic layers were washed with saturated saline and dried over anhydrous sodium sulfate. The solvent was distilled away under reduced pressure and a white solid of 5-fluoro-6-(2H-1,2,3-triazol-2-yl)nicotinic acid (198 mg) was thus obtained.
