The microwave-induced synthesis of N-substituted 2,3-pyridinedicarboximides (1) by means of two different approaches is presented. One involves direct N-alkylation of quinolinimide (2) (Method A) and the other, dehydrative condensation of quinolinic anhydride (4) and amines (Method B). Reactions resulted highly accelerated, with improved yields in relation to those obtained by conventional heating. The scope and limitations of each method and its variants are discussed.
