Participants

Reaction Steps

A 5M sodium hydroxide aqueous solution (2 ml) was added to a THF/MeOH (2 ml/2 ml) solution containing methyl 5-fluoro-6-(2-methoxyethoxy)nicotinate (264 mg) obtained in the 2nd step, followed by stirring at room temperature for 1 hour. Next, 6M hydrochloric acid (2 ml) was added to the reaction solution at 5° C. or less 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-(2-methoxyethoxy)nicotinic acid (197 mg) was thus obtained.
