Procedure

Compound 408 (110 mg, 0.343 mmol) was dissolved in methanol (10 mL), and potassium hydroxide (20.0 mg, 0.356 mmol) was added thereto, followed by stirring under heating and reflux for 2.5 hours. Water was added to the reaction mixture, followed by extraction with ethyl acetate. The organic layer was 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=1:1) to afford the entitled Compound 409 (124 mg, 0.343 mmol).
