Procedure

To a solution of 367 (70.0 mg, 0.172 mmol) in dimethyl sulfoxide (0.439 mL, 6.18 mmol) and treated with a solution of potassium carbonate (65.5 mg, 0.474 mmol;) in water (0.433 mL, 24.0 mmol;). After cooling at 0° C., hydrogen peroxide (0.540 mL, 7.04 mmol) was added slowly. The reaction was complete by LCMS at 15 min. Saturated sodium bisulfite (0.894 g, 8.59 mmol) was added and the reaction mixture extracted into ethyl acetate. The organics were washed with brine, dried over sodium sulfate and concentrated to give crude C which was submitted to reverse-phase HPLC to give 379 (27% yield). MS: (ESI+)=426.1
