Procedure
9-Bromo-1,2-dihydrobenzo[b]pyrrolo[3,2,1-jk][1,4]benzodiazepin-6-thione (4 g), hydrazine hydrate (4 ml) and benzene (150 ml) were combined and refluxed overnight. The reaction mixture was concentrated to approximately 50 ml and, after standing overnight, the precipitate was filtered. Recrystallization of the filter cake from chloroform/ether gave 2.35 g (59.5%) of product, mp 260° C. (dec).
