反応手順

To a slurry of lithium aluminum hydride (0.45 g, 11.9 mmol) in anhydrous diethyl ether (40 mL) at 0° C., a solution of methyl 4-chloro-pyridine-2-carboxylate (2.0 g, 11.7 mmol) in diethyl ether (30 mL) was added. The resulting mixture was stirred at room temp. overnight, and quenched with successive addition of water (0.45 mL), 15% aqueous NaOH (0.45 mL), and water (1.35 mL). The resultant slurry was stirred at room temp. for 30 min., and filtered through a small plug of Celite. The filtrate was washed with brine, dried over anhydrous magnesium sulfate, filtered, and concentrated under vacuum to provide 4-chloro-2-hydroxymethylpyridine.
