Procedure

To a suspension of pyridinium chlorochromate (PCC) (5 g) in CH2Cl2 (200 mL) and 4 angstrom molecule sieves (5 g) was added the alcohol (2 g) (Step II). The mixture was stirred 2 hr at RT, filtered through celite and evaporated. Flash chromatography using 25% ethyl acetate in hexane afforded the title compound.
