실험 절차

Compound 178a (3.0 g) obtained in Step A was dissolved in acetone (30 ml), mixed with Jones reagent (2.6 M) (4.9 ml), and stirred at room temperature for 2 hours. The reaction solution was concentrated under reduced pressure. The resulting residue was mixed with water and extracted with ethyl acetate. The organic layer was washed with a saturated aqueous sodium chloride solution, dried over magnesium sulfate anhydride, and evaporated under reduced pressure for removing the solvent. The residue was purified by silica gel column chromatography (hexane/ethyl acetate=4/1) to give Compound 178 (3.0 g, 75%) as colorless crystals.
