Acetonitrile → HCID 15867815, compound

Participants

Reaction Steps

To a solution of ice-cooled acetonitrile (1 mL) and pyridine (0.1 mL) was added a hydrogen fluoride-pyridine solution (0.1 mL). To this solution was added methyl (11R,12S,13E,15S,17R)-9-acetyl-11,15-bis(tert-butyldimethylsiloxy)-17,20-dimethyl-7-thiaprosta-8,13-dienoate (12 mg, 0.019 mmol) in pyridine (0.1 mL). The ice bath was removed and the solution was agitated for 15 hours, while returning it to room temperature. The reaction solution was poured into a mixture of ethyl acetate and a saturated aqueous sodium hydrogencarbonate. The desired product was extracted from this mixed solution of ethyl acetate. The extract was washed with brine, then dried over anhydrous sodium sulfate. The solution was concentrated under reduced pressure, then subjected to thin layer chromatography for separation (ethyl acetate:hexane=3:1) to obtain methyl (11R,12S,13E,15S,17R)-9-acetyl-11,15-dihydroxy-17,20-dimethyl-7-thiaprosta-8,13-dienoate (3.2 mg, 39%).
