To this is added dropwise a solution of lithium borohydride (2.0M in THF, 6.09 mL). The solution was allowed to warm to room temperature and stirred for 1 hour. The reaction was quenched with water (20 mL) then evaporated to dryness. The residue was dissolved in ethyl acetate (150 mL) and washed with water (150 mL) followed by brine (50 mL). The organics were concentrated in vacuo to give to the desired compound (2.44 g) as white solid.
