Reaction Steps

A mixture of step B product, 2-17-c, (2.0 g, 5 mmol) and Dess-Martain reagent (2.4 g, 5.6 mmol) in DCM (60 mL) was stirred at the ambient temperature for 1 h. The reaction solution was evaporated under vacuum to give a residue, which was purified by column chromatography with the eluent DCM:MeOH=60:1 to afford the crude product, 2-17-d, (1.84 g, 84%) as a solid. LC-MS: (M+H3O)+ 416.
