الإجراء التجريبي

Under argon, 915 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 was stirred at room temperature for 17 hours with 19 ml of a mixture of acetic acid/water/tetrahydrofuran (65/35/10). The mixture was evaporated thereafter under vacuum and the residue purified by column chromatography on silanized silica gel with ethanol/water (1:1), thus obtaining 94 mg of the title compound.
