Procedure
To a solution of EXAMPLE 308A (314 mg) in dichloromethane (5 mL) was added cyclobutanone (70 mg) followed by sodium triacetoxyborohydride (318 mg). The mixture was stirred overnight. The mixture was diluted with dichloromethane (300 mL) and washed with aqueous NaHCO3, water and brine and dried over Na2SO4. After filtration, evaporation of solvent gave the title compound.
