Procedure

Pyridinium chlorochromate (301.5 mg) was added to a solution of 2-acetamido-1,3-diacetoxy-2-(8-hydroxytetradecyl)propane (300 mg) in dichloromethane (19 ml) and the mixture was stirred at room temperature for 2 hours in a stream of nitrogen. Ether (38 ml) and magnesium sulfate (appropriate amount) were added thereto and the mixture Was stirred for 10 minutes. The reaction mixture was suction-filtered and the filtrate was concentrated. The concentrate was extracted with ethyl acetate and the ethyl acetate layer was washed with 1N hydrochloric acid, a saturated sodium hydrogencarbonate solution and saturated brine in order. The resultant mixture was dried over magnesium sulfate. The solvent was distilled away to give the subject compound (290 mg).
