Description
Verfahren zur Herstellung von 1.4-Bis-dimethylaminoacetogy-2-methyl- naphthalin-chlormethylat. Bekanntlich zeigt die dem Vitamin K zugehörige Grundsubstanz, das.
2-Methyl-1,4- naphthochinon sowie dessen Hydrierungs,- produkt, das Methylnaphthohylrochinon, und deren Analoges, eine mehr oder weniger aus gesprochene Vitamin K-Wirkung. Da diese Substanzen in Wasser unlöslich bezw. als Alkalisalze wohl löslich, aber sehr un beständig .sind, sind sie nur auf peroralem Wege oder vermittelst Verabreichung in öliger Lösung anwendbar.
Es besteht daher .der Wunsch nach Präparaten mit Vitamin K Wirkung, welche auch in Form ihrer wässerigen Lösungen beständig und parente- ral anwendbar sind.
Man hat bereits vorgeschlagen: alkylierte 1,4-Naphthohydrochinone mit Anhydriden organischer zweibasischer Säuren zusammen zuschmelzen und aus dem Reaktionsprodukt das überschüssige Anhydrid mit Wasser aus zuwaschen.
Es wurde nun gefunden, dass man wasser- lösliche, .die Wirkung des Vitamins K zei gende Verbindungen ,aus 2@-Alkyl-1,4-naphtho- chinonen. oder -hydrochinonen erhält, wenn man in diese Verbindungen vermittelst der Carbonyl- bezw. der Hydrogyl'gruppen was serlöslich machende Reste einführt, wobei die Veresterung von 2-Alkyl-1,
4-naphthohydro- chinonen mit Anhydlriden organischer zwei basischer Säuren ausgeschlossen sein soll. Man gelangt zu den neuen Verbindungen auf sehr mannigfaltige Weise.
Zum Beispiel kann man die Hydrochinonedieser Reihe mittels eines Halogenacetylhalogenids, wie Chl;oracetylchlorid, Bramacstylbromid, Chlor- propionylohlorid u.
a., höher halogenierter Säurehalogemde in die zugehörigen chloTier- ten Ester überführen, und diese mit H,ega- methylentetramin, Trimethylamin oder einem andern tertiären Amin, wie z. B. Dimethyl- äthyllamin oder Tmiäthylamin zum Um- Setzung bringen, wodurch die quaternären Verbindungen entstehen.
Mit gleichem oder ähnlichem Erfolge kann man 2-Alkylnaph- thohydrochinon mit Anhydriden oder Chlori den anorganischer, mehrbasischer Säuren, wie Phosphoroxychlorid usw. umsetzen, wo durch man Estersäuren erhält, die in Form ihrer Salze, z. B. ihrer Alkalimetallcalze, wie des Natrium- und galiumsalizes sowie des Ammoniumsalzes in Wasser löslich sind.
Oder man kann die 1,4-Naphthochinone mit Hydrazinverbindungen, welche eine wasser- löslichmachende Gruppe tragen, umsetzen, z. B. mit dem Chlormethylat von Dimethyl- aminoessigsäurehydrazid. Ferner lassen sich wasserlösliche Verbindungen dieser Art durch Umsetzung der Chinone mit Alkali- bisulfit erhalten.
Es war überraschend, dass die Verbindun gen vom Typus des Methylnaphthochinons sich in eine wasserlösliche Form überführen lassen, ohne ihre Vitamin K-Eigenschaften zu verlieren.
Gegenstand des vorliegenden Patentes ist ein Verfahren zur Herstellung von 1,4-Bis- dimethylaminoacetoxy- 2 -me@thyl-naphthalin- chlorm,ethylat, welches dadurch gekennzeich net ist, dass man Chloracetyl-halogenid auf 1,4-Dioxy-2-methyl-naphthalsn einwirken lässt und die erhaltene Chloracetylverbindung mit Trimethylamin umsetzt.
<I>Beispiel:</I> 70 Gewichtsteile 1,4-Dioxy-2-methyl- naphthalin werden mehrere Stunden lang mit 200 Vtilumteilen Chloracetylchlorid im Öl bad auf<B>12,0-130'</B> C erhitzt. Nach dem Ab kühlen giesst man auf Eis und saugt die ab geschiedene feste Substanz ab. Diese löst man alsdann in Äther, schüttelt sie mit Biear- bonatlösung aus und trocknet sie mit Chlor calcium.
Beim Eindampfen der Lösung er hält man die Chloracetylverbindung, die beim Uml.öe#en aus Chloroform-Gasolin farb lose Nädelehen mit dem Schmelzpunkt 113 C bildet.
9,8 Gewichtsteile der Chlor- acetylverbindung werden in 60 Volumteilen Essigsäureä.thylester gelöst und mit 35 Vo- lumteilen einer 15 % igen Lösung von Tri- methylamin in Benzol, versetzt. Allmählich Seheiden sich Kristalle des Chlormethylats in sehr guter Ausbeute ab.
Sie bilden nach dem Umlösen aus absolutem Alkohol-Essig- ester farblose, leicht wasserlösliche Nädel- chen vom Zersetzungspunkt 220-221 C. Das Produkt hat die Formel:

Process for the preparation of 1,4-bis-dimethylaminoacetogy-2-methyl-naphthalene-chloromethylate. It is well known that the basic substance associated with vitamin K shows that.
2-methyl-1,4-naphthoquinone and its hydrogenation product, methylnaphthohylroquinone, and its analogues, a more or less pronounced vitamin K effect. Since these substances are insoluble in water respectively. as alkali salts are soluble, but very unstable, they can only be used perorally or by administration in an oily solution.
There is therefore a desire for preparations with vitamin K action, which can also be used consistently and parenterally in the form of their aqueous solutions.
It has already been proposed that alkylated 1,4-naphthohydroquinones should be melted together with anhydrides of organic dibasic acids and the excess anhydride was washed out of the reaction product with water.
It has now been found that water-soluble compounds, which show the effect of vitamin K, can be obtained from 2 @ -alkyl-1,4-naphthoquinones. or hydroquinones obtained when one in these compounds mediating the carbonyl or. the Hydrogyl'gruppen which introduces water-solubilizing radicals, the esterification of 2-alkyl-1,
4-naphthohydroquinones with anhydrides of organic two basic acids should be excluded. There are many ways to get to the new connections.
For example, the hydroquinones of this series can be prepared using a haloacetyl halide such as chloroacetyl chloride, bramacstyl bromide, chloropropionyl chloride and the like.
a., convert higher halogenated acid halides into the associated chlorinated esters, and these with H, egamethylene tetramine, trimethylamine or another tertiary amine, such as. B. Dimethyl- äthyllamin or Tmiäthylamin bring about the implementation, whereby the quaternary compounds arise.
With the same or similar success you can implement 2-Alkylnaph- thohydroquinone with anhydrides or Chlori the inorganic, polybasic acids, such as phosphorus oxychloride, etc., where ester acids are obtained in the form of their salts, eg. B. their alkali metal calcium, such as the sodium and galium salts and the ammonium salt are soluble in water.
Or the 1,4-naphthoquinones can be reacted with hydrazine compounds which carry a water-solubilizing group, e.g. B. with the chloromethylate of dimethyl aminoacetic acid hydrazide. Furthermore, water-soluble compounds of this type can be obtained by reacting the quinones with alkali bisulfite.
It was surprising that the compounds of the methylnaphthoquinone type can be converted into a water-soluble form without losing their vitamin K properties.
The subject of the present patent is a process for the preparation of 1,4-bis-dimethylaminoacetoxy-2-methylnaphthalene-chloromethylate, which is characterized in that one chloroacetyl halide on 1,4-dioxy-2- methyl naphthalene can act and the chloroacetyl compound obtained reacts with trimethylamine.
<I> Example: </I> 70 parts by weight 1,4-dioxy-2-methylnaphthalene are heated to <B> 12.0-130 '</B> C for several hours with 200 parts by volume of chloroacetyl chloride in an oil bath. After cooling, it is poured onto ice and the solid substance which has separated out is filtered off with suction. This is then dissolved in ether, shaken out with carbonate solution and dried with calcium chloride.
When the solution is evaporated, the chloroacetyl compound is retained, which forms colorless needles with a melting point of 113 ° C when the solution is poured from chloroform-gasoline.
9.8 parts by weight of the chloroacetyl compound are dissolved in 60 parts by volume of ethyl acetate, and 35 parts by volume of a 15% solution of trimethylamine in benzene are added. Gradually, crystals of the chloromethylate separate out in a very good yield.
After dissolving from absolute alcohol / ethyl acetate, they form colorless, easily water-soluble needles with a decomposition point of 220-221 C. The product has the formula:
