Abstract:
There are provided a novel process for producing [{(5Z,7E)-(1S,3R,20S)-1,3-dihydroxy-9,10-secopregna-5,7,10(19),16-tetraen-20-yl}oxy]-N-(2,2,3,3,3-pentafluoropropyl)acetamide, which process is characterized by irradiating a compound represented by the formula: with UV to ring-open the compound, and then isomerizing the resulting compound; an intermediate useful for carrying out the process; and a process for producing the intermediate.
