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是可选取的取代o-苯基,基团R1和R2中的一个是氢或低碳基,另一个是可选取代的C-取代哌啶基,该基团可在与苯并[b]噻吩基团相连的环C原子上携带羟基,或者从该C原子发出可选的C-C双键,且该基团可在N原子上携带脂肪族性质的碳氢基团,该基团可在1-位以上的位置取代;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。它们可用作药物制剂的活性成分,用于治疗精神抑郁和精神病。
