The invention relates to a process for the production of new benzo[b]thiophenes of formula I ##SPC1## wherein PH is optionally substituted o-phenylene, one of the radicals R.sub.1 and R.sub.2 is hydrogen or lower alkyl, and the other of the radicals R.sub.1 and R.sub.2 is optionally C-substituted piperidyl which optionally carries hydroxy on the ring-C-atom bound to the benzo[b]thienyl radical, or which optionally contains a C-C-double bond emanating from this C-atom, and which optionally carries on the N-atom a hydrocarbon radical of aliphatic character, which radical is optionally substituted in a position higher than the 1-position, and of their acid addition salts. These new compounds possess valuable pharmacological properties. In particular they inhibit mono-amine oxidase and further inhibit the absorption of noradrenaline and serotonine in the brain. They are useful as active substances for pharmaceutical preparations for the treatment of mental depressions and psychoses.
本发明涉及一种生产新的苯并[b]噻吩的方法,其化学式为I ##SPC1## 其中 PH 可选地被取代为 o-苯基,基团 R.sub.1 和 R.sub.2 中的一个是氢或低碳基,另一个是可选的C-取代哌啶基,该基团可在与苯并[b]噻吩基团结合的环-C-原子上携带羟基,或者可选地从该C-原子发出一个C-C-双键,并在N-原子上携带具有脂肪性特征的碳氢基团,该基团在高于1-位置的位置上可选地被取代,以及它们的酸加成盐。这些新化合物具有有价值的药理特性。特别是它们抑制单胺氧化酶并进一步抑制脑内去甲肾上腺素和5-羟色胺的吸收。它们可用作制备用于治疗心理抑郁和精神病的药物制剂的活性物质。
