Procedure

Compound 71 (112 mg, 0.286 mmol), sodium tungstate (10 mg, 0.02 mmol), 30% hydrogen peroxide (130 μL, 1.14 mmol), methanol (2.0 mL), and ethyl acetate (20 mL) were combined under Argon and heated to reflux for 3d. The solution was cooled, poured into water and extracted several times with ethyl acetate. The combined organic extracts were dried with anhydrous sodium sulfate. Removal of the solvent in vacuo gave 72 as a solid: 109 mg (0.259 mmol, 91%)
