该中间体在本合成路线中的序号：(III)

Alkylation of 4-amino-3-nitrophenol (I) with 1-(2-chloroethyl)piperidine (II) provides ether (III). Subsequent nitro group reduction in (III) to afford diamine (IV) is performed by means of zinc powder in AcOH. Coupling of diamine (IV) with 2-chloroquinoline-3-carboxylic acid (V) furnishes amide (VI). Then, intramolecular cyclization of amino amide (VI) with Burgess reagent, followed by hydrolysis in boiling 6 M HCl gives rise to the title benzimidazolyl quinolinone.
