Procedure

At 40°, 300 mg. of (5Z,13E)-(8R,11R,12R,15S)-1-(N-methylcarbamoyloxy)-11,15-bis(tetrahydropyran-2-yloxy)-5,13-prostadien-9-one was agitated with 9 ml. of a mixture of glacial acetic acid/water/tetrahydrofuran (65/35/10) for 6 hours. The mixture was then evaporated to dryness under vacuum. After purifying the residue by chromatography on silica gel (ether/ethyl acetate 7+3), 145 mg. of the title compound was obtained as a colorless oil.
