Novel synthesis of the pharmacologically important 1-substituted-6-phenyl-4H-s-triazolo[4,3-α][1,4]benzodiazepines

Several 6-phenyl-4H-s-triazolo[4,3-α][1,4]benzodiazepines have useful biological activity both in experimental animals and in man. This manuscript describes a novel synthesis of these compounds from intermediates that do not have a pre-formed benzodiazepine ring system.

8-Chloro-1-methyl-6-phenyl-4H-s-triazolobenzodiazepines with Substituents at C-4

A series of 8-chloro-1-methyl-6-phenyl-4H-s-triazolobenzodiazepines with substituents at C-4 was prepared and evaluated for antianxiety potential.It was found that substitution at this position generally decreased the activity in this series.
