실험 절차

103 mg of (13E)-(8R,9R,11R,12R,15S,16RS)-9-chloro-11,15-bis(tetrahydropyran-2-yloxy)-16,19-dimethyl-13,18-prostadienoic acid methylsulfonylamide was stirred for 24.5 hours under argon at room temperature with 1.9 ml of a mixture of acetic acid/water/tetrahydrofuran (65/35/10). Then the mixture was concentrated under vacuum and the residue purified by column chromatography on silica gel with hexane/0-100% ethyl acetate as the eluent, thus obtaining 34.3 mg of the title compound.
