Procedure

To a solution of EXAMPLE 265H (320 mg) in dichloromethane (5 mL) was added 1,3-difluoroacetone (139 mg) and sodium triacetoxyborohydride (157 mg). The mixture was stirred overnight. The mixture was diluted with ethyl acetate (200 mL) and washed with 2N aqueous NaOH, water and brine. After drying over Na2SO4, the mixture was filtered and the solvent was evaporated under vacuum to provide the title compound.
