Procedure

To a solution of EXAMPLE 494F in dichloromethane (120 mL) at 0° C. was added Dess-Martin periodinane (17.7 g) and the reaction was allowed to warm to room temperature. The reaction was diluted with dichloromethane (200 mL), washed twice with saturated aqueous NaHCO3 solution and brine, dried over Na2SO4, filtered, and concentrated. The crude product was filtered through a silica gel plug to give the title compound.
