実験手順

104 mg of the alcohol was dissolved in 5 ml of chloroform and stirred with 445 mg of the Dess-Martin reagent (periodinane) at room temperature for 30 minutes. The reaction solution was poured into a mixture of saturated aqueous sodium hydrogencarbonate and saturated aqueous sodium thiosulfate and extracted with ethyl acetate. The organic layer was dried over anhydrous magnesium sulfate. The desiccant was filtered off, and the solvent was distilled off under reduced pressure. The residue was purified by silica gel column chromatography [hexane/ethyl acetate=10/1] to give 52 mg of the title compound as a colorless oily substance.
