Abstract (en)

[origin: FR2764601A1] The invention concerns a method for preparing a compound of formula (I) in which: R<1> represents a C1-C10 alkyl group, linear or branched, an aralkyl group in which the alkyl part is linear and comprises 1 to 3 carbon atoms and the aryl part is selected among the phenyl groups, substituted or not, in particular by one or several C1-C3 alkyl groups, or by several halogen atoms or by one or several nitro radicals; R<2> represents a C1-C16 alkyl group, linear or branched. The compounds of formula (I) are synthesis intermediates useful in particular for preparing quinoline or quinolone derivatives such as 4-hydroxyquinoline-3-carboxylic acid esters.
