Procedure

Ex-5) To a solution of the product of Example 4 in anhydrous THF was added lithium borohydride (21.5 mL, 43 mmol). This solution was stirred for 16 hours at 25° C. The lithium borohydride was quenched with methanol and the solvent was removed under reduced pressure. The residue was dissolved in ethyl acetate, washed twice with potassium hydrogen sulfate and twice with brine. The organic phase was dried over magnesium sulfate and all solvent was removed under reduced pressure to yield the title compound.
