The transposing of isomer yields in the methanolyses of N-substituted quinolinimides by triethylamine

The effect of triethylamine in transposing the respective yields of the two isomeric esters ensuing from the methanolysis of  N -substituted quinolinimides is described and is rationalized with a mechanism. Keywords: N -Substituted quinolinimides, methyl 2-carbamoyl-3-pyridinecarboxylates, methyl 3-carbamoyl-2-pyridinecarboxylates, benzenesulfonamide derivatives, triethylamine-induced rearrangements, reaction mechanisms
