Abstract

New compound with the general formula I ## Chemical formula (where A represents group C2-4 straight or branched alkylines R to the power 1 and R to the 2 power may be the same or different, and each Hydrogen agent, halogen, little alkyl or little alkyl, or R to the power 1 and R to the second power together form methylene dioxin, R to the power 3 and R to the fourth power can be the same or different, and each agent C1-5 alkyl or C3-6 cycloalkyl or R to the power 3 and R to the fourth power together with the nitrogen atoms they connect to. It forms a 4-7 ring, which may contain either an oxygen or sulfur atom or another nitrogen atom. That ring and the latter nitrogen atom may be chosen to have a C1-3 alkyl or benzyl group) and salt formed by a chemically acceptable acidification and Quaternary ammonium salts of that substance having the A valuable and useful study, especially in sedative, sedative, anti-depressive, anti-epileptic, anti-Parkinson's, local anesthetic pain, suppressant secretion and / Or resist pain syndrome and convulsions New compounds with the general formula I may be prepared by a known method.
