该中间体在本合成路线中的序号：(VI)Diazotization of 2-chloro-5-nitroaniline (I), followed by quenching with a solution of SO2 in HOAc in the presence of CuCl2, furnished the sulfonyl chloride (II). Treatment of (II) with aqueous ammonia gave rise to the corresponding sulfonamide (III). The chloro group of (III) was then displaced with cyclohexylamine (IV) in refluxing 3-chlorotoluene to afford the cyclohexylamino benzenesulfonamide (V). Finally, condensation of sulfonamide (V) with pentyl isocyanate (VI) produced the target sulfonylurea.
