A process to make 6-phenyl-4H-s-triazolo[4,3-a][1,4]-benzodiazepines by converting 2-[3-(hydroxymethyl)-4H-1,2,4-triazol-4-yl]benzophenones to 2-[3-[(phthalimido or methanesulfonyl)methyl]-4H-1,2,4-triazol-4-yl]benzophenones and converting these compounds to the highly active 6-phenyl-4H-s-triazolo[4,3-a][1,4]benzodiazepines useful as tranquilizers and sedatives.
将2-[3-(羟甲基)-4H-1,2,4-三唑-4-基]苯酮转化为2-[3-[(邻苯二甲酰亚胺或甲磺酰基)甲基]-4H-1,2,4-三唑-4-基]苯酮,然后将这些化合物转化为作为镇静剂和催眠剂有用的高活性6-苯基-4H-s-三唑并[4,3-a][1,4]-苯二氮䓬。
