该中间体在本合成路线中的序号：(VII)4,5-Dimethoxy-2-nitrobenzoic acid (I) was treated with thionyl chloride to form acid chloride (II), followed by reaction with ammonia to yield 4,5-dimethoxy-2-nitrobenzamide (III). This was reduced with sodium borohydride in the presence of copper sulfate to give aminobenzamide (IV), which was refluxed with formic acid to afford 6,7-dimethoxyquinazoline-4(3H)-one (V). Subsequent treatment of (V) with phosphoryl chloride gave the chloroquinazoline (VI). The title compound was then prepared by condensation of (VI) with 2-bromo-4-aminophenol (VII) in refluxing ethanol.
