Van Es, Theodorus published the artcileN,1-Dialkyl-7-(alkylamino)-4-(alkylimino)-1,4-dihydroquinoline-3-carboxamides and their 4-oxo derivatives: synthesis and properties, Computed Properties of 924-99-2, the publication is South African Journal of Chemistry [online computer file] (2001), 1-16, database is CAplus.
Methods are described for accessing the little known class of 4-alkyliminoquinoline-3-carboxamide title compounds; viz., from 4-oxoquinoline-3-carboxylic acids treated successively with thionyl chloride and amine, from 4-oxoquinoline-3-carboxylic esters treated likewise, and from the hydrogen chloride salt of a 4-alkyliminoquinoline-3-carboxylic ester and amine. Mechanistic aspects of the syntheses are discussed, and some spectroscopic and chem. properties of the title compounds are presented.
