실험 절차
3-tetrahydro-2H-2-pyranyloxy-5-(tert.butyldimethylsilyloxy)-(1S,3R,5R)-cyclohexylacetate (6, 3.5 parts, 9.16 mmol) was dissolved in dry methanol (25 parts). To the solution anhydrous potassium carbonate (0.828 parts, 6 mmol) was added and the mixture was stirred at room temperature for 2 hr. Methanol was removed under vacuum and residue was extracted several times with dichloromethane. Dichloromethane layers were combined and washed with water followed by brine wash. It was dried on anhydrous sodium sulfate. Solvent was removed under vacuum and residue was purified by flash column chromatography to yield 3-tetrahydro-2H-2-pyranyloxy-5-(tert.butyldimethylsilyloxy)-(1S,3R,5R)-cyclohexan-1-ol (7, yield 3 parts, 96%).
