该中间体在本合成路线中的序号：(VIII)Alternatively, acid chloride (IV), prepared from 2-chloronicotinic acid (III), was treated with methanol and triethylamine to afford the methyl ester (VIII). Displacement of the 2-chloro with m-(trifluoromethyl)aniline (VII) yielded methyl niflumate (IX). Finally, transesterification of methyl ester (IX) with 2-morpholinoethanol (V) in the presence of sodium metal gave rise to the title compound.
