Solvent-free synthesis of 5-(aryl/alkyl)amino-1,2,4-triazines and α-arylamino-2,2′-bipyridines with greener prospects

Abstract

A convenient approach towards 5-(aryl/alkyl)amino-1,2,4-triazines and α-arylamino-2,2′-bipyridines was developed following <italic>ipso</italic>-substitution of a cyano-group by amino groups and, finally, aza-Diels-Alder reaction with 1-morpholynocyclopentene.
