実験手順

To a solution of EXAMPLE 75C (2.8 g) in dichloromethane (50 mL) was added Dess-Martin Periodinane (5.68 g). The reaction mixture was stirred at room temperature for 3 hours and diluted with ether and washed with 5% NaOH and brine. The organic layer was dried over Na2SO4, filtered, and concentrated. The residue was purified by flash chromatography using 20% ethyl acetate in hexanes to provide the title compound.
