The synthesis of novel pyrrolo[1,2-c][1,3]benzodiazepine and pyrrolo[3,2-c]- [1]benzazepine ring systems from (2-aminophenyl)(1H-pyrrol-2-yl)methanone and 2-[(1H-pyrrol-2-yl)methyl]aniline is presented, utilizing triphosgene as carbonylation-cyclization reagent for the formation of the 7-membered heterocycle. A study of the reaction shows that small changes in the reaction conditions affect dramatically
