Procedure
To a solution of alcohol compound from Step 2 (400 mg) was added Dess-Martin reagent (500 mg) and the mixture was stirred at rt for 3 h. After the reaction was complete the mixture was diluted with methylene chloride followed by the addition of 0.1 N NaOH aqueous solution (12 mL) and the stirring was continued for about 20 min. The organic phases were washed with 0.1 N NaOH solution, brine, dried over MgSO4, and concentrated under reduced pressure. The residue was purified by flash chromatographed (eluting with 5% methanol in methylene chloride). MS (ESI): 406.1 (M+H+)
