Unexpected synthesis of a 1H-pyrrolo[2,3-e]-1,2,4-triazine
Abstract
3,6-Dichloro-5-(2-pyrrolidin-1-ylcyclohept-l-enyl)-1,2,4-triazine was found to undergo a facile thermal intramolecular rearrangement; an X-ray crystal structure determination showed the product to be derived from a novel heterocyclic system, 1H-pyrrolo[2,3-e]-1,2,4-triazine.
