Pyridazino[1,2-a] 1,2,5-triazepines.
By the condensation of 1,2-di(chloracetyl)piperidazine with primary amines 3-substituted derivatives of 1,5-diketoperhydropyridazino[1,2-a] 1,2,5-triazepine (1--8, Fig. 1) were obtained. Some of them show sedative action at the 25--100 mg/k dosis level and are of low ip toxicity.
