1-Aryl-2,3,4,5-tetrahydro-1H-1,5-benzodiazepin-2-ones of the general formula ##STR1## wherein: R.sub.1 is hydrogen, 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 trifluoromethyl, 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-苯二氮平-2-酮,其中:R.sub.1为氢,低碳基,优选为1-3碳的低碳基或不饱和的2-3碳的低碳基;R.sub.2、R.sub.3、R.sub.4、R.sub.5相同或不同,分别为氢、卤素、低碳基,优选为甲基的低碳基、低碳氧基,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,分别为氢或低碳基,优选为甲基。该化合物通过在溶剂和碱的存在下脱卤化通式为##STR2##的取代2-(3'-卤代丙酰胺基)-二苯胺,其中R.sub.2到R.sub.9如上定义,X为卤素,使胺环化,然后烷基化以在5位氮原子上引入不饱和的低碳基R.sub.1,如果必要的话。该化合物具有抗惊厥、镇静和肌肉松弛作用。
