  Verfahren zur Herstellung neuer, spasmolytisch wirksamer Verbindungen
Die vorliegende Erfindung betrifft ein Verfahren zur r Herstellung neuer, spasmolytisch wirksamer Verbindungen.



   Im Schweizer Patent Nr. 371112 sind basische Ather entsprechend der Formel I beschrieben :
EMI1.1     
 worin Ri für Wasserstoff oder ein Halogen,   vorzwgs-    weise Chlor, steht,   R2    und R3 f r Wasserstoff oder niede, re Alkylreste mit 1-2   C-Atomen sttehen, woKi    mindestens einer dieser beiden Reste jedoch einem Alkylrest der erwÏhnten Art bedeutet, R4 f r   -CH=CH-oder-CH2-CH2-steht    und   R5    f r eine Dialkylaminogruppe, deren Alkylreste je 1-2 C Atome enthalten, oder f r einen 5- oder 6gliedrigen, ein Stickstoffatom enthaltenden und über das Stick  stoffatom    gebundenen heterocyclischen Rest steht.



   Es wurde   nunmehr gefunden, dass quatemäre    Ammoniumverbindungen dieser basischen ¯ther ebenfalls eine hohe. spasmolytische Wirksamkeit besitzen. Die gemäss der Erfindung herzustellenden quaternÏren Ammoniumverbindungen entsprechen der allgemeinen Formel II :

  Process for the production of new, spasmolytic compounds
The present invention relates to a process for the production of new, spasmolytically active compounds.



   Basic ethers according to formula I are described in Swiss patent No. 371112:
EMI1.1
 where Ri stands for hydrogen or a halogen, preferably chlorine, R2 and R3 stand for hydrogen or lower, more alkyl radicals with 1-2 C atoms, whereKi stands for at least one of these two radicals, however, an alkyl radical of the type mentioned, R4 for -CH = CH- or -CH2-CH2- and R5 represents a dialkylamino group, the alkyl radicals of which each contain 1-2 C atoms, or a 5- or 6-membered heterocyclic radical containing a nitrogen atom and bonded via the nitrogen atom.



   It has now been found that quaternary ammonium compounds of these basic ethers also have a high. Have spasmolytic effectiveness. The quaternary ammonium compounds to be prepared according to the invention correspond to the general formula II:
EMI1.2
 in which R6 stands for hydrogen or a halogen, preferably chlorine, R7 and R8 stand for hydrogen or lower alkyl radicals having 1-2 C atoms, but at least one of these two radicals is an alkyl radical of the type mentioned, R9 for -CH = CH- or -CH2-CH2-, R10 and R11 represent alkyl radicals with 1-2 C atoms or, together with the nitrogen atom to which they are bonded, a 5- or 6-membered heterocyclic radical containing a nitrogen atom, R12 represents alkyl radicals with 1-4 carbon atoms and X is a halogen atom.



   The 5- or 6-membered heterocyclic radical containing a nitrogen atom is preferably the piperidisno, morpholino and pyrrolidino radical in B. e. R12 is preferably methyl or ethyl.



   The new compounds of the formula II are prepared according to the invention by reacting a basic ether of the above formula I, preferably in the presence of an organic solvent, with a haloalkyl having 1-4 C atoms, preferably with heating, and the quaternene formed Ammonium compound is isolated from the reaction gemasch.



   The new products have a pronounced papaverine effect, combined with a good anti-cholinergic effect. The following table shows a comparison with quaternary compounds of known products of similar constitution. The listed in the table, inventu. Products manufactured in accordance with the formula III
EMI2.1

The respective meaning of R6, R7, R8 and R13 is given in the first four rows of the table.

   Row V of the table shows the anticholinergic activity index in comparison to atropine (= 1), measured on carbaminoylcholine chloride spasm using a concentration of 10-7 g / ml. Row VI of the table shows the myotropic effect compared to papaverine (= 1), measured using a concentration of 4. 10-4 BaCl2 g / ml.



  Row VII of the table shows the histamine-antagonistic effect in comparison with diphenhydramine (= 1), measured at a concentration of 1. 10-6 histamn g / ml.

All experiments were carried out on the isolated guinea pig.



   The table shows that the new products have a papaverine effect that is 10 to 20 times greater than the papaverine effect of the previously known products in which R7 and R8 stand for hydrogen.



  The anticholinergic effect of the new products is about the same as that of atropine.



   Example 1 ¯-Dimethylamino-ethyl- (6-methyl-2,5-endomethylene-3-tetrahydrobenzhydryl) -ether-iodo-methylate
28.5 g (0.1 mol) of ¯-dimethylaminoethyl (6-methyl2, 5-endomethylene-3-tetrahydrobenzhydryl) ether are dissolved in 75 ml of ethyl acetate and mixed with
14.2 g (0.1 mol) of methyl iodide were added. After 24 hours, 250 ml of absolute ether are added, the precipitated salt is suctioned off and extracted from acetone or
Recrystallized ethyl acetate. 175-184¯C.



   Yield: 50-60 11 / o, of theory.



   For example, 2¯-piperidino-ethyl- (α-methyl-2,5-endomethylene-? 3-tetrahydrobenzhydryl) -ether-bromomethylate
32.5 g of ¯-piperidino-ethyl (α-methyl-2,5-endomethylene-ds-tetrahydrobenzhydxyl) ether are dissolved in 100 ml of ethyl acetate, mixed with 19 g of methyl bromide and heated to the boil for 5 minutes .



   After cooling, the precipitated salt is filtered off with suction and recrystallized from acetone with the addition of a little alcohol.



   Mp 220-222 C.



   Analogously to Examples 1 and 2, the following quarternary salts were prepared from the corresponding tertiary bases:
