Novel N-amino alkyl indole compounds are disclosed. These compounds correspond to the Formula I ##STR1## In said Formula R.sub.1 indicates the hydrogen atom, an alkyl group with 1 to 4 carbon atoms, which may be substituted by a phenyl group, or the acetyl group; R.sub.2 indicates the hydroxy carbonyl group, an alkoxy carbonyl group with 1 to 4 alkyl carbon atoms, the cyano group, the amino carbonyl group, a mono-alkyl amino carbonyl group with 1 to 4 alkyl carbon atoms, or a di-alkyl amino carbonyl group with 1 to 4 alkyl carbon atoms, with the proviso that, when R.sub.2 is the hydroxy carbonyl group, then R.sub.1 is other than the hydrogen atom; A indicates an alkylene group with 2 to 5 carbon atoms; R.sub.3 and R.sub.4 are the same or different substituents and indicate the hydrogen atom, an alkyl group with 1 to 4 carbon atoms, or R.sub.3 and R.sub.4 are an alkylene group forming, together with the nitrogen atom to which they are attached, a heterocyclic ring with 5 to 7 ring members; and R.sub.5 and R.sub.6 are the same or different substituents and indicate hydrogen and halogen atoms, alkyl groups with 1 to 3 carbon atoms, alkoxy groups with 1 to 3 carbon atoms, or one of said substituents R.sub.5 and R.sub.6 being the nitro group or the trifluoro methyl group while the other one is the hydrogen atom. The acid addition salts of said compounds are also disclosed. The above mentioned novel N-amino alkyl indole compounds have a favorable effect upon the motility of the gastro-intestinal tract. The compounds are obtained, for instance, by reacting the alkali metal salts of a corresponding indole compound which is unsubstituted at its nitrogen atom, with a halogeno alkyl amine.
本发明揭示了新型的N-氨基烷基吲哚化合物。这些化合物对应于公式I ##STR1## 在上述公式中,R.sub.1表示氢原子,具有1至4个碳原子的烷基,其可以被苯基取代,或乙酰基;R.sub.2表示羟基羰基基团,具有1至4个烷基碳原子的烷氧羰基基团,氰基,氨基羰基基团,具有1至4个烷基碳原子的单烷基氨基羰基基团或具有1至4个烷基碳原子的双烷基氨基羰基基团,但有条件限制,即当R.sub.2为羟基羰基基团时,R.sub.1不是氢原子;A表示具有2至5个碳原子的烷基;R.sub.3和R.sub.4是相同或不同的取代基,表示氢原子,具有1至4个碳原子的烷基,或R.sub.3和R.sub.4是形成与它们所连接的氮原子一起的杂环环的烷基;R.sub.5和R.sub.6是相同或不同的取代基,表示氢原子和卤素原子,具有1至3个碳原子的烷基,具有1至3个碳原子的烷氧基,或其中之一是硝基基团或三氟甲基基团,而另一个是氢原子。还揭示了该化合物的酸加成盐。上述新型的N-氨基烷基吲哚化合物对胃肠道的运动有良好的影响。例如,可以通过将未在其氮原子上取代的相应吲哚化合物的碱金属盐与卤代烷基胺反应来获得这些化合物。
