合成路线1
该中间体在本合成路线中的序号:(VI)Alkylation of 2,4-dichloro-6-nitrophenol (IV) with iodomethane in the presence of K2CO3 provides the methyl ether (V). Subsequent nitro group reduction in (V) employing iron powder and NH4Cl leads to aniline (VI). This is then acylated by sulfonyl chloride (III) to form sulfonamide (VII). The N-trichloroacetyl group of (VII) is finally removed by alkaline hydrolysis to provide the title compound
