α-halohydrazides react with 2-amino pyridine to give symetrically substituted N-amino maleimides. We have shown that this reaction proceeds through the formation of 4-hydroxy imidazopyridines. This result open a new route to dissymetrically substituted N-amino maleimides. The hydrolysis of N-amino maleimides is a good route to substituted maleic anhydrides.
