Abstract
A one-step procedure has been developed for the synthesis of previously unknown ethyl 5-(arylcarbamoyl)-6-methyl-2-oxo-1,2-dihydropyridine-3-carboxylates by reaction of ethyl 2-cyano-3-ethoxyprop-2-enoate with acetoacetanilides in the presence of a catalytic amount of piperidine in ethanol at room temperature.
