실험 절차

Compound 352 (155 mg, 0.298 mmol) and 0.1 mol/L hydrochloric acid (2.5 mL) were dissolved in ethanol (2.5 mL), followed by stirring at 90° C. for 2 hours. The reaction mixture was neutralized with a saturated aqueous solution of sodium hydrogencarbonate, followed by extraction with ethyl acetate. The organic layer was washed with a saturated aqueous solution of sodium chloride and dried over anhydrous magnesium sulfate, and then the solvent was distilled away under reduced pressure. The resulting residue was purified through silica gel column chromatography (hexane:ethyl acetate=1:4) to afford the entitled Compound 353 (89.0 mg, 82%).
