실험 절차
To a solution of compound 3 (2 g, 0.01 mol) in THF (20 mL) was added lithium aluminum hydride (0.63 g, 0.02 mol) at 0° C. and the mixture was stirred at room temperature for 30 min. Ethanol (10 mL) and saturated aqueous ammonium chloride solution (2.0 mL) were added to the reaction mixture. The precipitated insoluble material was filtered off, and the filtrate was concentrated under reduced pressure. The residue was subjected to silica gel chromatography (ethyl acetate:hexane=1:1) to give the title compound as a colorless oil.
