该中间体在本合成路线中的序号：(I)8-Methoxy-2-trifluoromethylquinoline-5-carboxylic acid (I) was activated as the corresponding nitrophenyl ester (III) upon treatment with p-nitrophenol (II) and EDC. The p-nitrophenyl ester (III) was then coupled with 4-amino-3,5-dichloropyridine (IV) in the presence of NaH to produce amide (V). The pyridine ring of (V) was finally oxidized to the title N-oxide by treatment with peracetic acid.
