合成路线1
该中间体在本合成路线中的序号:(VII)Reaction of 3,5-dichlorobenzamide (V) with pivalaldehyde (VI) in the presence of benzotriazole (VII) gives rise to the benzotriazolyl benzamide (VIII). This is then condensed with the diamino cyclobutene (IV) to afford the racemic adduct (IX), which is finally resolved into the enantiomers employing chiral chromatography.

合成路线2
该中间体在本合成路线中的序号:(XIII)Alkylation of benzotriazole (XIII) with chloroacetonitrile leads to a mixture of regioisomeric cyanomethyl derivatives (XIV) and (XV). The minor isomer (XV) is then condensed with aldehyde (XII) employing ethanolic KF to produce the substituted acrylonitrile (XVI). Finally, the acetamide function of (XVI) is converted into the target thioamide by treatment with Lawesson's reagent
