Maleimide derivatives are usually synthesized from maleic anhydride and a diamine to obtain the intermediates, maleamic acids which on cyclo-dehydration to a maleimide is a general method for the preparation. Numerous reagents or high pressure 32 used methods were reported for effective the dehydration of amic acids to imides. However in these methods that the synthesis leads to several by-products such as isoimides, acetanilides, maleimides, acetic acid adducts, and products with mixed functionalities which interns the yields are low . In an Alternate route, the displacement of methoxycarbonyl group of maleimide with nucleophilic group, such as amines under basic condition to get imides or N-alkylation with alkyl halides by using base in anhydrous conditions
