Procedure
The mixture of (4S,5R)-1-{(2R,9E)-11-[3,17β-bis-(benzyloxy)estra-1,3,5(10),9(11)-tetraen-11-yl]-2-(3,3,4,4,5,5,6,6,6-nonafluorohexyl)-9-undecenoyl}-3,4-dimethyl-5-phenylimidazolidin-2-one and (4S,5R)-1-{(2R,9Z)-11-[3,17β-bis(benzyloxy)estra-1,3,5(10),9(11)-tetraen-11-yl]-2-(3,3,4,4,5,5,6,6,6-nonafluorohexyl)-9-undecenoyl}-3,4-dimethyl-5-phenylimidazolidin-2-one (283 mg, 0.27 mmol) was dissolved in a mixed solvent of methanol (12 ml) and tetrahydrofuran (1.2 ml), followed by addition of palladium hydroxide/carbon (85 mg) at room temperature. After purging with hydrogen, the reaction mixture was stirred for 1 day at room temperature. After the reaction mixture was filtered, the solvent was concentrated under reduced pressure. The residue was purified by silica gel column chromatography (eluent: ethyl acetate/n-hexane=3/7) to give (4S,5R)-1-{(2R)-11-[3,17β-dihydroxyestra-1,3,5(10)-trien-11β-yl]-2-(3,3,4,4,5,5,6,6,6-nonafluorohexyl)undecanoyl}-3,4-dimethyl-5-phenylimidazolidin-2-one (164 mg, Yield 70%).
