Article abstract of DOI:10.1016/S0040-4020(01)85428-4

α-Halohydrazides react with 2-aminopyridine to give symmetrically substituted N-aminomaleimides.We have shown that this reaction proceeds through the formation of 4-hydroxyimidazopyridines.This result opens a new route to dissymetrically substituted N-aminomaleimides.The hydrolysis of N-aminomaleimides is a grood route to substituted maleic anhydrides.
