反应详情

Lithium aluminum hydride (410 mg, 10.8 mmol) was stirred in anhydrous THF (45 mL). A solution of ethyl 2,4-diethylpyridine-3-carboxylate (1.50 g, 7.2 mmol) in anhydrous THF (10 mL) was added at 0° C., and then stirred at room temperature for 2 hours. The reaction was quenched with an aqueous solution of sodium hydroxide and extracted 5 times with ethyl acetate. The combined organic phase was washed with brine and dried over sodium sulfate. After evaporation of the solvent, (2,4-diethylpyridin-3-yl)methanol was obtained as an oil (1.17 g, 98% yield) and used in the next step without further purification.
