  Verfahren zur Herstellung 6-basisch substituierter Morphanthridine Die Erfindung betrifft ein Verfahren zur Herstellung 6-basisch substituierter Morphanthridine der Formel:
EMI1.1     
 sowie von Säureadditionssalzen davon. In Formel I bedeutet R1 eine Alkyl- oder Hydroxyalkylgruppe mit 1 bis 3 C-Atomen, wobei letztere acyliert sein kann, oder eine Alkoxyalkylgruppe mit höchstens 5 C-Atomen,   R2    und   R.    sind gleich oder verschieden und bedeuten Wasserstoff oder Halogen. Allfällige Substituenten in den Benzolkernen befinden sich vorzugsweise in 3- oder 8-Stellung.



   Die gewünschten Produkte (I) werden erfindungsgemäss erhalten, wenn man Verbindungen der Formel:
EMI1.2     
 worin R2 und R3 die genannte Bedeutung haben, mit reaktionsfähigen Estern von Alkoholen der Formel   RI-OH,    worin R1 die genannte Bedeutung hat, umsetzt, wobei die Reaktionsgemische in Form der freien Basen oder von Säureadditionssalzen gewonnen werden.



  Als reaktionsfähige Ester von Alkoholen der Formel R1-OH kommen insbesondere Halogenwasserstoffsäureester in Betracht. Die Umsetzung erfolgt vorzugsweise in einem inerten Lösungsmittel, z. B. Benzol, durch Erwärmen auf Rückflusstemperatur.  



   Die in der beschriebenen Weise erhaltenen Basen sind in den meisten Fällen kristallisierbar, sonst im Hochvakuum unzersetzt destillierbar, und bilden mit anorganischen und organischen Säuren, beispielsweise Salzsäure, Bromwasserstoffsäure, Schwefelsäure, Salpetersäure, Phosphorsäure, Essigsäure, Oxalsäure, Weinsäure, To  luolsulfonsäure    und dergleichen, in Wasser beständige Additionssalze, in welcher Form die Produkte ebenfalls verwendet werden können.



   Die in der beschriebenen Weise erhaltenen Basen und ihre Säureadditionssalze sind neue Verbindungen, die als Wirkstoff in Arzneimitteln oder als Zwischenprodukte zur Herstellung von solchen Verwendung finden. Insbesondere fallen die Produkte als Neuroplegika, Neuroleptika und Analgetika in Betracht. Einzelne davon eignen sich zur Behandlung psychotischer Zustände. Diese Wirksamkeit äussert sich pharmakologisch in starker Motilitätsdämpfung bei Mäusen, die mit kataleptischer Wirkung einhergehen kann. Die Motilitätsdämpfung wird durch Messung der Laufaktivität nach der Methode von Caviezel und Baillod [Pharm. Acta Helv. 33, 469 (1958)] erfasst. Die Laufaktivitätswerte einiger erfindungsgemässer Produkte sowie deren Toxizität werden in der folgenden Tabelle I mit den entsprechenden Zahlen für Chlorpromazin verglichen.

Beispiel 1
Zu einer auf 600 C erwärmten Lösung von 5,54 g 6-(1-Piperazinyl)-morphanthridin in 50   ml    Benzol wird eine Lösung von 1,42 g Methyliodid in 30 ml Benzol getropft. Das Gemisch wird während 30 Minuten unter Rückfluss erwärmt. Nach dem Abkühlen nutscht man das Hydroiodid des Ausgangsmaterials ab und dampft das Filtrat im Vakuum zur Trockne ein.

   Der Rückstand wird aus Äther/Petroläther zur Kristallisation gebracht und aus Aceton/Petroläther umkristallisiert, wobei man 2,4 g   6-(4-Methyl 1 -piperazinyl)-morphanthridin    vom Schmelzpunkt   137,5-138,50    C erhält.



   In analoger Weise wie im vorerwähnten Beispiel erhält man aus entsprechenden Ausgangsstoffen die in der nachfolgenden Tabelle II genannten Produkte. Darin haben R1, R2 und Rs die früher angegebene Bedeutung.

  Process for the preparation of 6-basic substituted morphanthridines The invention relates to a process for the preparation of 6-basic substituted morphanthridines of the formula:
EMI1.1
 as well as acid addition salts thereof. In formula I, R1 denotes an alkyl or hydroxyalkyl group with 1 to 3 carbon atoms, the latter can be acylated, or an alkoxyalkyl group with at most 5 carbon atoms, R2 and R. are identical or different and denote hydrogen or halogen. Any substituents in the benzene nuclei are preferably in the 3- or 8-position.



   The desired products (I) are obtained according to the invention when compounds of the formula:
EMI1.2
 in which R2 and R3 have the meaning mentioned, are reacted with reactive esters of alcohols of the formula RI-OH, in which R1 has the meaning mentioned, the reaction mixtures being obtained in the form of the free bases or of acid addition salts.



  Particularly suitable reactive esters of alcohols of the formula R1-OH are hydrohalic acid esters. The reaction is preferably carried out in an inert solvent, e.g. B. benzene, by heating to reflux temperature.



   The bases obtained in the manner described are in most cases crystallizable, otherwise they can be distilled without decomposition in a high vacuum, and form with inorganic and organic acids, for example hydrochloric acid, hydrobromic acid, sulfuric acid, nitric acid, phosphoric acid, acetic acid, oxalic acid, tartaric acid, toluenesulfonic acid and the like, addition salts stable in water, in which form the products can also be used.



   The bases obtained in the manner described and their acid addition salts are new compounds which are used as active ingredients in medicaments or as intermediates for the preparation of such use. In particular, the products come into consideration as neuroplegics, neuroleptics and analgesics. Some of them are suitable for the treatment of psychotic states. This efficacy manifests itself pharmacologically in a strong reduction in motility in mice, which can be associated with cataleptic effects. The motility damping is determined by measuring the running activity according to the method of Caviezel and Baillod [Pharm. Acta Helv. 33, 469 (1958)]. The running activity values of some products according to the invention and their toxicity are compared in Table I below with the corresponding figures for chlorpromazine.

example 1
A solution of 1.42 g of methyl iodide in 30 ml of benzene is added dropwise to a solution, heated to 600 ° C., of 5.54 g of 6- (1-piperazinyl) -morphanthridine in 50 ml of benzene. The mixture is refluxed for 30 minutes. After cooling, the hydroiodide of the starting material is suction filtered and the filtrate is evaporated to dryness in vacuo.

   The residue is crystallized from ether / petroleum ether and recrystallized from acetone / petroleum ether, 2.4 g of 6- (4-methyl 1 -piperazinyl) morphanthridine having a melting point of 137.5-138.50 ° C. being obtained.



   In a manner analogous to that in the aforementioned example, the products listed in Table II below are obtained from appropriate starting materials. Here R1, R2 and Rs have the meaning given earlier.



  In the right column, acetone means acetone, ether, Ch chloroform and Pe means petroleum ether.
