Description
Verfahren zur Herstellung neuer quaternärer Verbindungen der heterocyclischen Reihe Gegenstand der Erfindung ist ein Verfahren zur Herstellung von 2,2'-R-bis-Phthalazinium-Verbin- dungen, wobei R einen zweiwertigen Kohlenwasser stoffrest darstellt, und. den sich von ihnen ableitenden Pseudobasen und deren Anhydroverbindungen.
In diesen Verbindungen können die Phthalazin- reste beliebig substituiert sein, z. B. auch ankonden- sierte Ringe aufweisen; vorzugsweise sind sie jedoch unsubstituiert. Der Kohlenwasserstoffrest R ist vor zugsweise ein aliphatischer Kohlenwasserstoffrest, ins besondere ein gerader oder verzweigter Alkylenrest. Dieser Alkyienrest weist mit Vorteil nicht über 30 Kohlenstoffatome auf;
bevorzugt sind Alkylen- reste mit 4-10 Kohlenstoffatomen, wie Tetra- methylen, Hexamethylen oder Decamethylen.
Die neuen Verbindungen besitzen bakterio- statische Eigenschaften, so z. B. gegenüber Staphylo- coccus aureus, und können als Desinfektionsmittel oder Heilmittel verwendet werden. Sie verstärken ausserdem die durch Antigene ausgelösten immuni- satorischen Reaktionen, indem sie z. B. die Antikör perbildung verstärken. Sie können dementsprechend z. B. als Zusätze zu Vaccinen angewendet werden.
Besonders wertvoll sind die Phthalazinium-Ver- bindungen der Formel
EMI0001.0037
worin n eine ganze Zahl von 4-10, vor allem 6 oder 10 bedeutet und A das Anion einer Säure darstellt. Geeignete Anionen sind beispielsweise diejenigen starker anorganischer Säuren, wie der Halogenwasser stoffsäuren, z. B. Salz-, Bromwasserstoff- oder Jod- wasserstoffsäure, der Schwefelsäure oder Anionen von organischen Säuren, wie Alkylsulfonsäuren, z. B. der Methan- oder Äthansulfonsäure, oder Arylsulfon- säuren, z.
B. p-Toluolsulfonsäure oder Naphthalin- sulfonsäure, oder der Essigsäure, Oxalsäure, Wein säure, Zitronensäure, Benzoesäure oder Naphthaiin- carbonsäuren., oder Anionen von Alkylschwefelsäuren, wie z. B. der Methylschwefelsäure.
Das erfindungsgemässe Verfahren zur Herstellung der neuen Verbindungen ist dadurch gekennzeichnet, dass man gegebenenfalls an den Ringkohlenstoff atomen substituierte X-R-Phthalaziniumverbindungen, wobei X eine reaktionsfähig veresterte Hydroxyl- gruppe bedeutet, und R die oben genannte Bedeutung besitzt, mit Phthalazin oder einem an den Ring- kohlenstoffatomen substituierten Phthalazin umsetzt.
Reaktionsfähig veresterte Hydroxylgruppen sind insbesondere mit starken anorganischen oder orga nischen Säuren, z. B. Halogenwasserstoffsäuren, wie Salz- oder Brom- oder Jodwasserstoffsäure, oder Sulfonsäuren, wie Benzolsulfonsäuren, veresterte Hydroxylgruppen.
Die Quaternisierung kann in An- oder Abwesen heit von Lösungsmitteln, bei Zimmertemperatur oder erhöhter Temperatur, im offenen oder geschlossenen Gefäss unter Druck vorgenommen werden.
Je nach den Reaktionsbedingungen werden die neuen Verbindungen als quaternäre Salze oder in Form der Pseudobasen, die je nach der Natur des Restes R Wasser abspalten und so .in die Anhydro- verbindungen übergehen können, .gewonnen. Die Salze lassen sich durch Behandlung mit Alkalien, wie Alkalicarbonaten oder -hydroxyden oder anderen ge eigneten Metallhydroxyden oder -carbonaten, oder Anionenaustauschern in die Pseudobasen oder gege benenfalls die entsprechenden Anhydroverbindungen überführen.
Aus den Pseudobasen oder derenAnhydro- verbindungen lassen sich durch Behandlung mit Säu- ren, wie der Halogenwasserstoffsäuren, Schwefelsäure, Salpetersäure, Phosphorsäure, Essigsäure, Propion- säure, Oxalsäure, Apfelsäure., Weinsäure, Zitronen säure, Methansulfonsäure, Äthansulfonsäure, Oxy- äthansulfonsäure, Benzoesäure,
Methyl- oder Äthyl- schwefelsäure, Salicylsäure, p-Aminosalicylsäure oder Toluolsulfonsäure, die entsprechenden Salze gewinnen. Erhaltene quatemäre Salze lassen sich auch durch Behandlung mit Anionenaustauschern in andere Salze überführen.
Die Ausgangsstoffe sind zum Teil bekannt; sofern sie neu sind, lassen sie sich nach an sich bekannten Methoden herstellen.
Neben ihrer Anwendung als Zusätze zu Impf stoffen können die neuen Verbindungen als desinfi zierende Mittel in Form technischer Präparate oder als Heilmittel, z. B. in Form pharmazeutischer Prä parate, Verwendung finden.
In den nachstehenden Beispielen sind die Tempe raturen in Celsiusgraden angegeben.
<I>Beispiel 1</I> 2,3 g ss-Chloräthyl-phthalaziniumchlorid werden zusammen mit 1,3 g Phthalazin in 50 cm3 Acetonitril gelöst. Die Lösung wird während 14 Stunden am Rückfluss gekocht und darauf auf 0 abgekühlt. Die ausgefallenen Kristalle putscht man ab und kristalli siert sie aus AlkohoI um. Man erhält so das Äthylen- bis-(phthalaziniumchlorid) der Formel
EMI0002.0036

In analoger Weise erhält man Tetramethylen-bis- (phthalaziniumchlorid), F. 284-285 , Hexamethylen- bis-(phthalaziniumchlorid), F.240 und Decamethylen- bis-(phthalaziniumchlorid), F. l82-183 .
Das als Ausgangsmaterial verwendete ss-Chlor- äthylphthalaziniumchlorid kann wie folgt erhalten werden: 26 g Phthalazin und 16 cm3 Äthylenchlorhydrin in 150 cm3 abs. Toluol werden während 10 Stunden am Rückfluss gekocht. Darauf kühlt man auf 0 ab und putscht die ausgefallenen Kristalle ab.
Das so erhaltene ss-Hydroxyäthyl-phthalaziniumchlorid der Formel
EMI0002.0060
vom F. 232-234 lässt sich gegebenenfalls aus Alko hol umkristallisieren. 5,0g der rohen Verbindung werden in 50 cm3 Thionylchlorid während 2 Stunden am Rückfluss gekocht. Man dampft die Lösung darauf im Vakuum zur Trockene ein und löst die zurück bleibenden Kristalle aus abs. Alkohol/Ather um.
Man erhält so ss - Chloräthyl-phthalaziniumchlorid der Formel

vom F. 277-278 . Die wässrige Lösung dieser Ver bindung wird mit Soda alkalisch gemacht.
Man erhält Anhydro - 2,2' - äthylen - bis - (1- oxy - 1,2 - dihydro- phthalazin) der Formel
EMI0002.0090
als farblose Nadeln, vom F. 146-148 , aus dem sich mit Säuren Äthylen-bis-phthalaziniumsalze, wie das Brorriid, Jodid, Sulfat, Nitrat, Tartrat usw. herstellen lassen.
Das als Ausgangsmaterial verwendete ss-Brom- äthyl-phthalaziniumbromid kann wie folgt erhalten werden: 2,1 g des nach Beispiel 1 hergestellten ss-Hydroxy- äthyl-phthalaziniumchlorids werden mit 20 cm3 48 %aiger wässeriger Bromwasserstoffsäure vermischt und während 20 Stunden im Einschlussrohr auf 180 erhitzt. Die Lösung wird darauf im Vakuum zur Trockene verdampft.
Man erhält ein dunkel gefärbtes Öl, das nach dem Versetzen mit wenig Aceton einen Kristallkuchen bildet; diesen löst man aus Alkohol/ Äther um und erhält so ss-Bromäthyl-phthalazinium- bromid der Formel

The quaternization can be carried out in the presence or absence of solvents, at room temperature or at elevated temperature, in an open or closed vessel under pressure.
Depending on the reaction conditions, the new compounds are obtained as quaternary salts or in the form of pseudobases which, depending on the nature of the radical R, can split off water and thus convert into the anhydro compounds. The salts can be converted into the pseudobases or, if appropriate, the corresponding anhydro compounds, by treatment with alkalis, such as alkali metal carbonates or hydroxides or other suitable metal hydroxides or carbonates, or anion exchangers.
From the pseudobases or their anhydro compounds, treatment with acids such as hydrohalic acids, sulfuric acid, nitric acid, phosphoric acid, acetic acid, propionic acid, oxalic acid, malic acid., Tartaric acid, citric acid, methanesulfonic acid, ethanesulfonic acid, oxyethanesulfonic acid, Benzoic acid,
Methyl or ethyl sulfuric acid, salicylic acid, p-aminosalicylic acid or toluenesulfonic acid, the corresponding salts are obtained. Quaternary salts obtained can also be converted into other salts by treatment with anion exchangers.
Some of the starting materials are known; if they are new, they can be produced by methods known per se.
In addition to their use as additives to vaccines, the new compounds can be used as disinfecting agents in the form of technical preparations or as medicines, eg. B. in the form of pharmaceutical prep, use.
In the examples below, the temperatures are given in degrees Celsius.
<I> Example 1 </I> 2.3 g of ss-chloroethyl phthalazinium chloride are dissolved together with 1.3 g of phthalazine in 50 cm 3 of acetonitrile. The solution is refluxed for 14 hours and then cooled to 0. The precipitated crystals are popped off and crystallized from alcohol. The ethylene bis (phthalazinium chloride) of the formula is obtained in this way
EMI0002.0036
from F. 218-220o ,.
Tetramethylene bis (phthalazinium chloride), F. 284-285, hexamethylene bis (phthalazinium chloride), F. 240 and decamethylene bis (phthalazinium chloride), F. 182-183, are obtained in an analogous manner.
The s-chloroethylphthalazinium chloride used as the starting material can be obtained as follows: 26 g of phthalazine and 16 cm3 of ethylene chlorohydrin in 150 cm3 of abs. Toluene are refluxed for 10 hours. It is then cooled to 0 and the crystals which have precipitated out are popped off.
The β-hydroxyethyl phthalazinium chloride of the formula obtained in this way
EMI0002.0060
from F. 232-234 can optionally be recrystallized from alcohol. 5.0 g of the crude compound are refluxed in 50 cm3 of thionyl chloride for 2 hours. The solution is then evaporated to dryness in a vacuum and the remaining crystals are dissolved from abs. Alcohol / ether around.
This gives ss - chloroethyl phthalazinium chloride of the formula
EMI0002.0072
as hygroscopic crystals from F.178-179 (dec.).
<I> Example 2 </I> 1.0 g of ss-bromoethyl phthalazinium bromide is refluxed together with 0.4 g of phthalazine in 20 cm 3 of acetonitrile for 6 hours. Then you cool down, clean the precipitated crystals and dissolve them from alcohol. This gives ethylene bis (phthalazinium bromide) of the formula
EMI0002.0083
from F. 277-278. The aqueous solution of this compound is made alkaline with soda.
Anhydro-2,2'-ethylene-bis- (1-oxy-1,2-dihydrophthalazine) of the formula is obtained
EMI0002.0090
as colorless needles, from F. 146-148, from which ethylene-bis-phthalazinium salts such as broride, iodide, sulfate, nitrate, tartrate, etc. can be produced with acids.
The β-bromo-ethyl-phthalazinium bromide used as starting material can be obtained as follows: 2.1 g of the β-hydroxy-ethyl-phthalazinium chloride prepared according to Example 1 are mixed with 20 cm3 of 48% aqueous hydrobromic acid and dissolved in the containment tube for 20 hours 180 heated. The solution is then evaporated to dryness in vacuo.
A dark-colored oil is obtained which, when mixed with a little acetone, forms a crystal cake; This is dissolved from alcohol / ether and thus obtained ss-bromoethyl-phthalazinium bromide of the formula
EMI0002.0111
from F. 155 (decomp.).
