실험 절차

In analogy to Example 1, 150 mg (0.29 mmol) of (8S,11R,13S,14S,17S)-17-hydroxy-11-[4-((RS)-1-hydroxyethyl)phenyl]-1 3-methyl-17-pentafluoroethyl-1,2,6,7,8,11,12,13,14,15,16,17-dodecahydrocyclopenta[a]phenanthren-3-one were converted using 3,3-dimethylbutyryl chloride and, after workup and purification, 113 mg (63%) of the title compounds were isolated as a colourless foam.
