Abstract 11‐Amino‐5H‐dibenzo[b,e]‐1, 4‐diazepines V, several of which possess neuroleptic properties, have been prepared using three methods: Aminolysis of either iminothioethers IV (X = methyl or an activating group such as cyanomethyl and p‐nitrobenzyl) or the iminochlorides III. Bischler‐Napieralski type cyclodehydration of o‐anilinophenyl‐ureas IX (only applicable for the synthesis of compounds V where R is other than hydrogen). Cyclodehydration of amino‐amides VII by various condensing agents.
