合成路线1
该中间体在本合成路线中的序号：(III)Acylation of 4-bromo-2-nitroaniline (I) with 5-chlorothiophene-2-sulfonyl chloride (II) in pyridine affords sulfonamide (III). The nitro group of (III) is then reduced to amine (IV) by means of hydrazine hydrate in the presence of Raney nickel. Further acylation of amine (IV) with sulfonyl chloride (II) furnishes the target bis-sulfonamide.
