合成路线1
该中间体在本合成路线中的序号：(XIV)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：(A)Condensation of S-(4-monomethoxytrityl)-L-cysteine (I) with 2-naphthalenesulfonyl chloride (II) under Schotten-Baumann conditions afforded sulfonamide (III). Cleavage of the trityl group of (III) by treatment with trifluoroacetic acid and triisopropylsilane gave thiol (IV), which was protected as the thiopyridyl derivative (V) using dithiodipyridine. Coupling of (V) with 4-amidinophenylalanyl piperidine (VI) by means of 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide - HCl (EDC), 1-hydroxybenzotriazole (HOBt) and N-ethylmorpholine (NEM) furnished dipeptide (VII). The thiopyridyl group of (VII) was then deprotected by treatment with tributyl phosphine to afford thiol (VIII).
