The invention discloses substituted 2H,3H-2,1-benzisothiazole-S-oxides having pharmacological activity in animals and useful as CNS depressant agents. The compounds may be prepared by reacting a substituted 2H,3H-2,1-benzisothiazole with an oxidizing agent. The substituted 2H,3H-2,1-benzisothiazole may be prepared by reacting a substituted .alpha.-methylthio-o-toluidine with one equivalent of an oxidizing agent, followed by treatment with base.
这项发明揭示了具有动物药理活性并且作为中枢神经系统抑制剂有用的取代的2H,3H-2,1-苯并异噻唑-S-氧化物。这些化合物可以通过将取代的2H,3H-2,1-苯并异噻唑与氧化剂反应来制备。取代的2H,3H-2,1-苯并异噻唑可以通过将取代的α-甲基硫氧-o-甲苯胺与一个氧化剂当量反应,然后进行碱处理来制备。
