실험 절차

Lithium aluminum hydride (299 mg, 7.87 mmol) was suspended in anhydrous diethyl ether (10 ml) under a nitrogen atmosphere, and a solution of the obtained 3-(t-butyldiphenylsiloxy)-3-(4-pyridyl)propionitrile (1.00 g, 2.59 mmol) in anhydrous diethyl ether (15 ml) was added dropwise to the suspension under ice-cooling with stirring over eight minutes. The temperature was raised to room temperature, and the mixture was stirred for 75 minutes. The reaction mixture was cooled with ice, ethyl acetate (15 ml) was added to the reaction mixture, and water (0.28 ml), a 15% aqueous sodium hydroxide solution (0.28 ml) and water (0.85 ml) were added thereto successively. The temperature was raised to room temperature, and the whole was stirred for 10 minutes. The reaction mixture was dried over anhydrous magnesium sulfate, the solvent was evaporated under reduced pressure, and the residue was purified by silica gel column chromatography to give the titled compound (180.0 mg, yellow oily matter, 17.8%).
