Tepoxalin, a potent anti-inflammatory agent, and its analogs can be synthesized by condensing an appropriate arylhydrazine hydrochloride and a 6-aryl-4,6-dioxohexanoic acid in alcohol with a base catalyst. These diarylpyrazolylpropanoic acids can be converted to their N-methylhydroxamic acids by generating the requisite acid chloride, and allowing it to react with N-methylhydroxylamine.
