Reaction Steps
To a solution of methyl 5-acetylpyridine-3-carboxylate (0.15 g, 0.84 mmol) in methanol (2.10 mL) was added aqueous 1N sodium hydroxide solution (2.51 mL, 2.51 mmol). The resulting mixture was stirred at room temperature for 1 hour, then concentrated under reduced pressure to give a residue that was acidified with aqueous 1 N hydrogen chloride solution and extracted with ethyl acetate. The organic extracts were combined, dried over magnesium sulfate, filtered and concentrated to provide the title compound: 1H NMR (500 MHz, CDCl3) δ 9.43 (d, J=1.4 Hz, 1 H), 9.36 (s, 1 H), 8.84 (s, 1 H), 2.70 (s, 3 H).
