合成路线1
该中间体在本合成路线中的序号：(VI)Treatment of aniline (I) with hexafluoroacetone trihydrate (II) and p-toluenesulfonic acid affords derivative (III), which is then derivatized with trifluoroacetic anhydride (IV) to provide trifluoroacetanilide derivative (V). Reduction of (V) by means of LiAlH4 in refluxing THF yields N-trifluoroethylaniline derivative (VI), which is finally converted into the target sulfonamide by reaction with benzenesulfonyl chloride (VII) in pyridine.
