Reaction Steps

To a solution of EXAMPLE 65C (3.86 g) in acetone (5 mL) and water (5 mL) was added pyridinium p-toluenesulfonate (120 mg). The mixture was stirred at 100° C. in a Biotage Initiator microwave reactor for 10 minutes. The mixture was diluted with ethyl acetate (200 mL) and washed with water and brine and dried over Na2SO4. Filtration and evaporation of the solvent gave the crude product which was used without further purification in the next reaction.
