Procedure

To a solution of Compound 16 (60 mg, 0.12 mmol) in dry CH2Cl2 (1 mL) was added mCPBA (77%, 33 mg, 0.146 mmol) at 0° C. and the resulting mixture was stirred at this temperature for 30 min. The reaction mixture was diluted with CH2Cl2 and water. The organic layer was washed with water and brine, dried over Na2SO4, filtered, and concentrated under reduced pressure. Purification of the residue by flash column chromatography (silica gel, 5% MeOH/EtOAc) gave compound 54 (7 mg). MS m/z (M+Na+) 510.0, MS m/z (M+Na+) 532.0.
