合成路线1
该中间体在本合成路线中的序号：(IX)Reaction of 2-chloronitrobenzene (I) with the sodium alkoxide of 2,2,2-trifluoroethanol (II) in cold THF afforded trifluoroethyl ether (III). The nitro group of (III) was then reduced by means of iron and AcOH to produce 2-(trifluoroethoxy)aniline (IV). Condensation of (IV) with diethyl (2-ethoxyethyl)malonate (V) in boiling diphenyl ether led to the furoquinolinone system (VI), and subsequent reaction of (VI) with 2-methyl-4-methoxyaniline (VII) in refluxing diethylene glycol generated the pyrroloquinolinone (VIII). Chlorination of (VIII) with POCl3 gave chloropyrroloquinoline (IX). Finally, displacement of the chlorine of (IX) by ethanolamine at 180 C yielded the title compound.
