Procedure

To a solution of EXAMPLE 265C (8.0 g) in dichloromethane (200 mL) was added Dess-Martin Periodinane (11.2 g). The mixture was stirred overnight. The mixture was diluted with ethyl acetate (400 mL) and washed with 2N aqueous NaOH, water, and brine. After drying over Na2SO4 and filtration, concentration of the solvent gave the crude product which was used directly in the next reaction without further purification.

Workup
