실험 절차

156 mg of (5Z,13E)-(8R,9R,11R,12R,15S,16RS)-9-chloro-11,15-bis(tetrahydropyran-2-yloxy)-16,19-dimethyl-5,13,18-prostatrienoic acid methylsulfonylamide was stirred for 16 hours under argon at room temperature with 3 ml of a mixture of acetic acid/water/tetrahydrofuran (65/35/10). The mixture was then evaporated under vacuum and the residue purified by column chromatography on silica gel with methylene chloride/5-30% isopropanol as the eluent, thus obtaining 62 mg of the desired compound.
