Versuchsvorschrift

Compound 587 (500 mg, 1.27 mmol) was dissolved in chloroform (13 mL), and m-chloroperbenzoic acid (219 mg, 1.27 mmol) was added thereto, followed by stirring at room temperature for 3 hours. The reaction mixture was poured into water, followed by extraction with chloroform. 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 (ethyl acetate) to afford the entitled Compound 591 (359 mg, 69%).
