The possibility of preparing 1,2,3,4,6,7,8,9-octahydro-5H-pyrrolo[3,2-c:4,5-c']dipyridines using the Piloty-Robinson reaction has been studied under various conditions. A novel method is proposed for the synthesis of the aromatic 3,6-diazacarbazole (5H-pyrrolo[3,2-c:4,5-c']dipyridine) from 2,8-dibenzoyl-1,2,3,4,6,7,8,9-octahydro-5H-pyrrolo[3,2-c:4,5-c']dipyridine obtained for the first time by the
