A useful synthetic principle for the preparation of N-heterocycles consists in the base treatment of azoma-lonates carrying electrophilic centers in the side chain. Thus, pharmacologically active triazolo[1,4]benzodiazepine-carboxamides can be prepared in one step from azomalonates derived from 2-aminobenzophenones and diethyl (2-chloroacetamido)malonate. The same malonate coupled with diazotized
