Compounds of the formula ##STR1## wherein R.sub.1 is hydrogen or alkyl of 1 to 4 carbon atoms; R.sub.2 is 2-, 3- or 4-pyridyl, phenyl or mono- or di- substituted phenyl, where the substituents are each individually alkoxy of 1 to 2 carbon atoms, fluorine, chlorine, bromine, trifluoromethyl, alkyl or 1 to 4 carbon atoms, hydroxyl or nitro; and R.sub.3 and R.sub.4 are each independently hydrogen or alkyl of 1 to 4 carbon atoms; or R.sub.3 and R.sub.4, together with each other and the nitrogen atom to which they are attached, form an unsubstituted or methyl-substituted, saturated 5- or 6-membered heterocycle which may contain an additional oxygen or nitrogen heteroatom, or form an imidazole ring; where the aminomethyl substituent is attached to the 4- or 5-position or the pyrrolidine ring, and non-toxic, pharmacologically acceptable acid addition salts thereof. The compounds as well as the salts are useful as nootropics and antihypoxics.
公式为##STR1##的化合物,其中R.sub.1是氢或1到4个碳原子的烷基;R.sub.2是2-、3-或4-吡啶基、苯基或单取代或双取代苯基,所述取代基各自独立地为1到2个碳原子的烷氧基、氟、氯、溴、三氟甲基、1到4个碳原子的烷基、羟基或硝基;R.sub.3和R.sub.4各自独立地为氢或1到4个碳原子的烷基;或者R.sub.3和R.sub.4连同它们附着的氮原子一起形成一个未取代或甲基取代的饱和5-或6-成员杂环,该杂环可以包含一个额外的氧或氮杂原子,或形成咪唑环;其中氨甲基取代基附着在4-或5-位置或吡咯烷环上,并且其非毒性、药理学上可接受的酸盐。该化合物及其盐可用作智力增强剂和抗低氧剂。
