Reaction Steps

The product from Example 60A (1.0 g, 3.03 mmol) and borane tetrahydrofuran complex (6.06 mL, 6.06 mmol) were combined in tetrahydrofuran (15.15 mL) and heated at 50° C. for 2 hours, cooled, treated with 10 mL of methanol, heated at 50° C. for 1 hour, cooled and concentrated. The residue was partitioned between ethyl acetate and water. The organic layer was washed with saturated aqueous sodium chloride, dried (anhydrous Na2SO4), filtered, and concentrated. Purification by chromatography (silica gel, 0-50% ethyl acetate in heptanes) afforded the title compound (0.73 g, 76%).
