Reaction Steps

To the compound of step b (1.3 g, 5 mmol) in 40 mL CH2Cl2 containing 1.8 g celite was added 2.4 g pyridinium chlorochromate and the resulting reaction mixture was stirred at RT for 2 h. The CH2Cl2 solution was filtered through celite, washed with water, brine, dried and concentrated in vacuo. The residue was purified by flash chromatography with 10% ethyl acetate-hexane to give 1.1 g of the desired product as a light yellow solid, m.p. 62°-65° C.
