合成路线1
该中间体在本合成路线中的序号:(VII)4-Nitrophenethylamine (I) was acylated with propionyl chloride and the resulting amide (II) was reduced to amine (III) with borane-dimethyl sulfide complex in refluxing THF. Amine (III) was then protected as the tert-butyl carbamate (IV) using Boc2O in THF. Subsequent catalytic hydrogenation of the nitro group of (IV) over Pd/C furnished aniline (V), which was coupled with 4-(trifluoromethoxy)benzenesulfonyl chloride (VI) to yield sulfonamide (VII). The Boc protecting group of (VII) was finally removed by treatment with trifluoroacetic acid.
