该中间体在本合成路线中的序号：(VI)In a related procedure, the condensation of 2-aminobenzo[b]thiophene-3-carbonitrile (VI) with 2,4-difluoronitrobenzene (II) produced the diaryl amine (VII). Reduction of the nitro group of (VII) using sodium hydrosulfite yielded diamine (VIII). Subsequent cyclization of amino nitrile (VIII) upon acidic treatment gave rise to the tetracyclic system (IX). This was then treated with refluxing N-methylpiperazine (V) to provide the title compound.
