Procedure

To a suspension of the compound prepared in Example 308 (323 mg) and the compound prepared in Example 139 (267 mg) in 1,2-dichloroethane (10 mL) and N,N-dimethylformamide (4 mL) was added diisopropylethylamine (0.89 mL) and sodium triacetoxyborohydride (813 mg). The reaction mixture was stirred at room temperature for 18 hours. The mixture was diluted with ethyl acetate, washed with saturated aqueous sodium bicarbonate and brine. The organics were dried over magnesium sulfate, filtered and concentrated under reduced pressure to afford the crude material, which was purified by flash column chromatography (eluant: 50-75% ethyl acetate/hexane) to furnish the title compound (222 mg) with the following physical properties.
