Abstract

We present here an efficient and simple method for the N-alkylation of aromatic cyclic imides employing cesium carbonate as the base in anhydrous N,N-dimethylformamide at low temperatures (20-70 ˚C). The employment of microwave irradiation presents noteworthy advantages over conventional heating. The method is compatible with base labile functional groups.
