1-Aryl-2,3,4,5-tetrahydro-1H-1,5-benzodiazepin-2-ones of the general formula ##STR1## wherein: R.sub.1 is hydrogen, or unsaturated lower alkyl, preferably of 1-3 carbons, or unsaturated lower alkyl preferably of 2 - 3 carbons R.sub.2, r.sub.3, r.sub.4, r.sub.5 are the same or different and are each hydrogen, halogen, lower alkyl, preferably methyl, lower alkoxy, preferably methoxy, or trifluromethyl, and R.sub.6, r.sub.7, r.sub.8, r.sub.9 are the same or different and are each hydrogen or lower alkyl, preferably methyl. The compounds are prepared by dehydrohalogenating substituted 2-(3'-halogenopropionylamino)-diphenyl amines of the general formula ##STR2## wherein R.sub.2 to R.sub.9 are the same as defined above and X is halogen, in the presence of a solvent and a base, to cyclize the amines and then alkylating to introduce the unsaturated lower alkyl radical R.sub.1 on the nitrogen in the 5 position, if necessary. The compounds possess anticonvulsant, sedative and muscle relaxant properties.
通式为##STR1##的1-芳基-2,3,4,5-四氢-1H-1,5-苯并二氮平-2-酮,其中:R.sub.1是氢,或不饱和的低碳基,优选为1-3个碳,或不饱和的低碳基,优选为2-3个碳;R.sub.2,r.sub.3,r.sub.4,r.sub.5相同或不同,分别是氢,卤素,低碳基,优选为甲基,低烷氧基,优选为甲氧基,或三氟甲基;R.sub.6,r.sub.7,r.sub.8,r.sub.9相同或不同,分别是氢或低碳基,优选为甲基。该化合物通过在溶剂和碱的存在下去卤代2-(3'-卤代丙酰胺基)-二苯胺通式##STR2##,其中R.sub.2至R.sub.9如上定义,X为卤素,使胺环化,然后烷基化以在5位氮上引入不饱和的低碳基R.sub.1,必要时。该化合物具有抗惊厥、镇静和肌肉松弛作用。
