実験手順

To a solution of Intermediate 176a (1.10 g, 1.70 mmol) in DCM (25 mL) at 0° C. was added Dess-Martin periodinane (791 mg, 1.86 mmol) and the resulting red-brown solution stirred at 0° C. for 45 min. Sodium metabisulfite (920 mg), water (10 mL) and sat. aq. NaHCO3 solution (10 mL) were added and the mixture stirred at RT until gas evolution ceased (15 min). The mixture was diluted with water (25 mL) and extracted with DCM (2×25 mL). The combined organics were passed through a hydrophobic fit and concentrated in vacuo to leave the title compound as a glassy orange solid (1.10 g, 100%). LCMS (Method 3): Rt 3.91 min, m/z 647 [MH+].
