Participants

Reaction Steps

Compound 1 (89.6 mg, 0.215 mmol) obtained in Example 1 was dissolved in dichloromethane (5.0 mL). To the solution was added 65% meta-chloroperbenzoic acid (85.7 mg, 0.323 mmol) and the mixture was stirred at room temperature for 2 hours. The solvent was evaporated under reduced pressure. The residue was purified by preparative thin-layer chromatography (chloroform/methanol=9/1) to give Compound 2 (47.7 mg, 51% yield).
