1-Substituted-6-phenyl-4H-s-triazolo[4,3-a][1,4]benzodiazepines of the formula II: ##STR1## wherein R.sub.0 is selected from the group consisting of hydrogen, methyl, ethyl, fluorine, chlorine, and bromine, and X is selected from fluorine, chlorine, and bromine; wherein R.sub.1 is selected from the group consisting of hydrogen, alkyl of 1 to 3 carbon atoms inclusive; wherein R.sub.2, R.sub.3, R.sub.4, and R.sub.5 are selected from the group consisting of hydrogen, alkyl, as defined above, halogen, nitro, cyano, trifluoromethyl, and alkoxy, alkylthio, alkylsulfinyl, and alkylsulfonyl, in which the carbon chain moieties are of 1 to 3 carbon atoms, inclusive, are prepared by reacting a compound of the formula: ##STR2## wherein R.sub.1, R.sub.2, R.sub.3 R.sub.4, and R.sub.5 are defined as above, with an haloacyl chloride or haloacyl bromide of the formula ##STR3## wherein R.sub.o and X are defined as above and X' is chlorine or bromine. The new products of formula II including their pharmacologically acceptable acid addition salts are useful as sedatives, tranquilizers and muscle relaxants in mammals and birds, and if X.dbd.X".dbd.Cl or Br they are useful as intermediates for cyano, alkylthio and dialkylamino products of high sedative and tranquilizing activity.
公式II为1-取代-6-苯基-4H-s-三唑并[4,3-a][1,4]苯二氮平,其中R.sub.0选择自氢,甲基,乙基,氟,氯和溴的群体,并且X选择自氟,氯和溴; R.sub.1选择自1至3个碳原子的包括烷基的群体; R.sub.2,R.sub.3,R.sub.4和R.sub.5选择自氢,烷基,如上所定义,卤素,硝基,氰基,三氟甲基和烷氧基,烷硫基,烷基硫醇基和烷基磺酰基,其中碳链基团为1至3个碳原子,包括。通过将公式中的化合物与公式为的卤代酰氯或卤代酰溴反应制备公式II的新产物:其中R.sub.1,R.sub.2,R.sub.3,R.sub.4和R.sub.5如上所定义,R.sub.o和X如上所定义,X'为氯或溴。公式II的新产品及其药学上可接受的酸盐可用作哺乳动物和鸟类的镇静剂,安定剂和肌肉松弛剂,如果X.dbd.X".dbd.Cl或Br,则它们可用作高镇静和安定活性的氰基,烷硫基和二烷基氨基产物的中间体。
