Procedure

To a solution of ice-cooled acetonitrile (1 ml) and pyridine (0.1 mL) was added hydrogen fluoride-pyridine (0.1 mL). To this solution was added methyl (11R,12S,13E,15S,17R)-9-phenethyl-11,15-bis(tert-butyldimethylsiloxy)-17,20-dimethyl-7-thiaprosta-8,13-dienoate (52 mg, 0.072 mmol) in pyridine (0.1 mL). The ice bath was removed and the solution was agitated for 15 hours wile returning it to room temperature. The reaction solution was poured into a mixture of ethyl acetate and saturated aqueous sodium hydrogencarbonate. The desired product was extracted from this mixed solution by ethyl acetate. The extract was washed with brine, then dried over anhydrous sodium sulfate. The solution was concentrated under reduced pressure, then was purified by silica gel column chromotography (40 to 50% ethyl acetate/hexane) to obtain methyl (11R,12S,13E,15S,17R)-9-phenethyl-11,15-dihydroxy-17,20-dimethyl-7-thiaprosta-8,13-dienoate (32 mg, 90%).
