Versuchsvorschrift
A 5 N sodium hydroxide solution (147 μL) was added to a solution of methyl 3-methoxypyridine-2-carboxylate (112 mg) in methanol (2 mL), and the mixture was stirred at room temperature overnight. The excess of methanol was evaporated under reduced pressure, and the residue was diluted with water. The aqueous layer was washed with ether and then made weak acidic with 5 N hydrochloric acid. The aqueous layer was extracted with a THF-ethyl acetate mixed solvent, and then the organic layer was dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure to obtain the title compound (19 mg).
