合成路线1
该中间体在本合成路线中的序号：(XVI)2) The oxidation of 3-oxo-4-androstene-17beta-carboxylic acid (I) with KMnO4/NaIO4/Na2CO3 in refluxing tert-butanol/water affords the seco-steroid (VIII), which is cyclized with NH3 in ethylene glycol at 180 C, giving the 5-unsaturated steroid (IX). The hydrogenation of (IX) with H2 over PtO2 in acetic acid yields the saturated azasteroid (X), which is esterified with 2,2-dimethoxypropane/HCl in methanol to afford the corresponding methyl ester (XI). The dehydrogenation of (XI) with phenylseleninic anhydride in refluxing chlorobenzene gives the 1-unsaturated azasteroid (XII), which is hydrolyzed with KOH in refluxing methanol/water to yield the corresponding unsaturated free acid (XIII). The esterification of (XIII) with 2,2'-dipyridyl disulfide (XIV) by means of triphenylphosphine in toluene affords the 2-pyridyl thioester (XV), which is finally amidated with 2,5-bis(trifluoromethyl)aniline (III) by means of silver trifluomethanesulfonate in dichloromethane. 3) The previously obtained unsaturated free acid (XIII) can also be treated with SOCl2 in pyridine to give the corresponding acyl chloride (XVI), which is then condensed directly with 2,5-bis(trifluoromethyl)aniline (III) in pyridine.

合成路线2
该中间体在本合成路线中的序号：(VI)Title compound was prepared by two synthetic ways: 1) Treatment of hexafluorophenylpropanol (I) with KH and then with trifluoromethane- sulfonic anhydride gave triflate (II), which was converted into azide (III) by reaction with NaN3 in trifluoroacetic acid. Reduction of azide (III) with Raney-nickel in isopropanol afforded the corresponding amine, which was isolated as the hydrochloride salt (IV). Acid chloride (VI) was prepared from acid (V) by treatment with SOCl2. Then, condensation of (VI) with amine (IV) in the presence of pyridine provided the target amide.
