실험 절차

A solution of Example 445A (228 mg) and 1M borane in THF (1.2 mL) in THF (2 mL) at room temperature was stirred for 5 hours, and treated sequentially with 2M sodium carbonate (1 mL) and 33% hydrogen peroxide (1 mL). The mixture was heated to 60° C. for 1 hour, diluted with ethyl acetate (100 mL), washed with water (45 mL) and brine (10 mL), dried (MgSO4), filtered, and concentrated. The concentrate was purified by flash column chromatography on silica gel with 20-40% ethyl acetate/hexanes to provide the desired product.
