Pharmacologically valuable 3-(aminopropyl)-indoles have the general formula ##SPC1## In which R.sub.1 is phenyl, halophenyl, nitrophenyl, aminophenyl, loweralkoxyphenyl or pyridyl, R.sub.2 is hydrogen or methyl, R.sub.3 and R.sub.4 are each hydrogen or lower alkyl or taken together form a polymethylene group which may be interrupted by oxygen so that --NR.sub.3 R.sub.4 is a heteromonocycle having 5 or 6 nuclear atoms and R.sub.5 is hydrogen, fluorine, chlorine or methoxy. Especially interesting are those compounds in which at least one of R.sub.1 and R.sub.5 comprises a flourine atom and --NR.sub.3 R.sub.4 is pyrrolidino. The compounds are made by condensation of correspondingly substituted indolylacetones with amines HNR.sub.3 R.sub.4 in a reducing medium or, in certain cases, by reduction of correspondingly substituted indolylacetoximes with or without subsequent lower alkylation.
具有药理学价值的3-(氨基丙基)-吲哚具有通式##SPC1##,其中R1为苯基、卤代苯基、硝基苯基、氨基苯基、低级烷氧基苯基或吡啶基,R2为氢或甲基,R3和R4各自为氢或低级烷基,或者一起形成可能被氧中断的多甲撑基团,使得--NR3R4是一个具有5或6个核原子的杂单环,而R5为氢、氟、氯或甲氧基。特别有趣的是那些化合物,其中至少有一个R1和R5包含氟原子,且--NR3R4为吡咯烷基。这些化合物是通过将相应的取代吲哚基丙酮与胺HNR3R4在还原介质中缩合制备的,或者在某些情况下,通过还原相应的取代吲哚基丙酮肟,随后可能进行低级烷基化。
