实验步骤: A solution of intermediate 24-95 (2.0 g, 7.6 mmol) and pyridine (1.2 mL, 11 mmol) in DCM (100 mL) is treated in one portion with triphenylphosphine dibromide (4.8 g, 11 mmol) at 0° C. The mixture is allowed to stir for 30 min, then concentrated in vacuo. The resulting crude material is purified by column chromatography on silica gel (using a gradient of 5-60% EtOAc/heptane) to afford the title compound (2.2 g). concentrated in vacuo The resulting crude material is purified by column chromatography on silica gel (
