실험 절차
A solution (1.0 M, 2.4 ml) of tetrabutylammonium fluoride/tetrahydrofuran was added to a solution of 1-((tert-butyldiphenylsilyloxy)methyl)-2-chloro-4-(n-pentyl)benzene (890 mg) in tetrahydrofuran (4.5 ml) under ice-cooling, and the mixture was stirred for 2 hr. Water was added to the reaction mixture and the resulting product was extracted three times with ethyl acetate. The organic layers were combined and washed successively with diluted hydrochloric acid, a saturated aqueous solution of sodium hydrogencarbonate and saturated brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated and the residue was purified by silica gel column chromatography (hexane/ethyl acetate=7/1) to give the objective compound (345 mg) as a colorless oil.
