Versuchsvorschrift

Using as the material and reagent a hydrogen fluoride-pyridine solution (0.7 ml) and methyl(11R,12S,13E,15S,17R)-9-benzoyloxy-11,15-bis(tert-butyldimethylsiloxy)-17,20-dimethyl-7-thiaprosta-8,13-dienoate (734 mg), the same procedure as in Example 2 was performed to obtain methyl(11R,12S,13E,15S,17R)-9-benzoyloxy-11,15-dihydroxy-17,20-dimethyl-7-thiaprosta-8,13-dienoate (141 mg, 28%)
