Reactions of 7-chloro-5-phenyl-1,3-dihydro-1,4-benzodiazepin-2-thione (XVIII) and its 5-(2-chlorophenyl) analogue XIX with hydrazines of methylthio-, ethylthio-, cyclohexylthio-, phenylthio-, 4-tolylthio-, 4-chlorophenylthio-, benzylthio-, S-(2-dimethylaminoethyl)thio-, 2-furfurylthio- and 3-pyridylmethylthioacetic acid in boiling butanol gave substance VII and the title compounds VIII-XVII. The synthesis of hydrazines XXVIII-XXXII is described. The compounds prepared are very little toxic, have strong discoordinating activity and are very potent as anticonvulsant agents. In this line they are substantially more active than alprazolam (II) and are not far behind triazolam (III).
7-氯-5-苯基-1,3-二氢-1,4-苯并二氮杂硫杂环己烯-2-硫酮(XVIII)及其5-(2-氯苯基)类似物XIX与甲硫基、乙硫基、环己硫基、苯硫基、对甲苯硫基、对氯苯硫基、苄硫基、S-(2-二甲氨基乙基)硫基、2-呋喃基硫基和3-吡啶甲基硫基乙酸的肼在沸腾的丁醇中反应,得到物质VII和标题化合物VIII-XVII。描述了肼XXVIII-XXXII的合成。制备的化合物毒性很小,具有强烈的去协调活性,并且作为抗惊厥药物非常有效。在这方面,它们比阿普唑仑(II)活性更高,并且与三唑安定(III)相差无几。
