Zusammenfassung

Aus Isatosäureanhydriden erhält man durch Umsetzen mit 1,2-Dimethylhydrazin die entsprechenden 1′,2′-Dimethylanthranilsäurehydrazide, die sich mit Phosgen zu 1,3,4-Benzotriazepin-2,5-dionen cyclisieren lassen.

Abstract

By reaction of isatoic anhydrides with 1.2-dimethylhydrazine the corresponding 1′.2′-dimethylanthranilic acid hydrazides are formed. The reaction of the latter with phosgene yields 1.3.4-benzotriazepine-2.5-diones.
