Quinazolines and 1,4-benzodiazepines. 75. 7-Hydroxyaminobenzodiazepines and derivatives

Abstract
7-Nitro-substituted benzodiazepines were reduced with stannous chloride in a buffered system to the corresponding 7-hydroxyamino derivatives. These compounds were alkylated, acylated and converted to nitroso and azoxy derivatives. The rearrangement of a hydroxyamine to an aminophenol and its oxidation to an aminoquinone are also exemplified. The results of the pharmacological screening for CNS effects [in mice] are given.
