실험 절차

To a solution of the product of Step B (200 mg, 0.42 mmol) in DCM (5 mL) was added Dess-Martin periodinane (350 mg, 0.84 mmol) in portion at room temperature. The mixture was stirred at for 0.5 h, and then diluted with water (5 mL), extracted with ethyl acetate. The organic layers were washed with brine (5 mL), dried over sodium sulfate, filtered and evaporated. The residue was purified by silica gel chromatography (EA/PE=1:8) to afford the title compound. LC/MS m/z=468.2[M+H]+.
