Abstract

Abstract This paper deals with the preparation of ethyl benzofuro [3, 2-b] pyrrole-2- carboxylate, its hydrolysis, N-alkylation, and reduction. Also the synthesis of new heterocyclic systems, benzofuro [3, 2-b] pyrrole and 2H-dihydrobenzofuro [2', 3': 4, 5] pyrrolo [1, 2-d]-1, 2, 4-triazin-1-one, is described. The structure of 14 new substances was corroborated by IR, UV, 1 H NMR, 13 C NMR and electron impact mass spectra.
