Reaktionsschritte
Lithium aluminum hydride (345 mg, 9.10 mmol) was put under a nitrogen atmosphere, and anhydrous diethyl ether (10 ml) was added dropwise thereto under ice-cold water-cooling. Next, a solution of 2,2-dimethyl-3-(4-pyridyl)-3-(p-tolylsulfonyloxy)propionitrile (600 mg, 1.82 mmol) in tetrahydrofuran (10 ml) was added dropwise to the mixture. The whole was stirred at room temperature overnight, and water (324 μl), a 15% aqueous sodium hydroxide solution (324 μl) and water (972 μl) were added successively to the reaction mixture under ice-cold water-cooling while stirring it vigorously. The organic layer was dried over anhydrous magnesium sulfate and concentrated under reduced pressure, and the obtained concentrate was purified by silica gel column chromatography to give the target compound (83.0 mg, 0.505 mmol, 28%) as a pale yellow oily matter.
