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, 1H NMR, 13C NMR and electron impact mass spectra.
