Reaction Steps

To a stirred solution of compound 8 (19.3 g, 72.5 mmol) in MeOH (500 mL) was added a solution of OXONE (133 g) in water (500 mL) dropwise at rt in 1 h. The resulting mixture was stirred at rt for 4 h and then concentrated under reduced pressure. The slurry aqueous mixture was extracted with DCM (200 mL×4). The combined extracts were washed with brine (100 mL×2), dried over anhydrous MgSO4, filtered, and evaporated to afford sulfone 10 (19.8 g, 92%) as a white solid. ESI MS m/z 299.2 (M+H)+.
