Procedure

To a solution of silyl alcohol (Step V) (1.2 g) in THF (10 mL) and acetic acid (0.3 mL) was added tetrabutylammonium fluoride (3 mL of 1M solution). The reaction mixture was stirred 2 hrs, quenched with pH 7 buffer, extracted with ethyl acetate and the organic extract dried and evaporated. Flash chromatography using 25% ethyl acetate/hexane afforded the title compound.
