実験手順
2-Norbornane acetic acid (15 g, 97 mmol) was dissolved in anhydrous tetrahydrofuran (150 mL) and treated dropwise with lithium aluminum hydride (195 mL, 1 M in tetrahydrofuran) at 0° C. The reaction was stirred for three days then quenched by dropwise addition of water (50 mL). The reaction was diluted with diethyl ether (300 mL) and washed with water (3×200 mL). The combined organic phases were dried (MgSO4), filtered, and concentrated to yield an oil. The product was passed through a pad of silica gel to yield 2-bicyclo[2.2.1]hept-2-yl-ethanol as a colorless oil (13.1 g, 96%).
