Description

  

  Verfahren zur Darstellung des Chlorhydrates des     Diäthylaminoäthylkampferogimäthers.       Es wurde     gefunden,        da.ss        inan    zu technisch  wertvollen Produkten gelangt, wenn man       Ald-    oder     IKetoxime    in Basisehe     Oximäther     und deren Salze verwandelt. Auf diese  Weise gelingt es, zu wasserlöslichen     Sub-          tanzen    zu gelangen, die sich ohne Reiz  wirkung subkutan einspritzen lassen und  ,ich daher für pharmazeutische Zwecke  eignen.

   Die neuen Körper können nach den  für die Darstellung basischer Äther be  kannten Methoden gewonnen werden, indem  man zum Beispiel die Salze von     Oximen    mit       3minoallrylhalogeniden    umsetzt.  



  Gegenstand vorliegenden Patentes ist ein  Verfahren zur Darstellung des Chlorhydrats  des     Diäthylaminoäthylkampferoximäthers,     das dadurch gekennzeichnet ist, dass man       Kampferoxim    mit     diäthylaminoäthylierend     wirkenden Mitteln, zum Beispiel mit     Diäthyl-          aminoäthylhalogenid,    behandelt und die er  haltene Base, den     Diäthylaminoäthylkampfer-          oximäther,    in ihr Chlorhydrat     überführt.       Die neue Verbindung ist in Wasser und  Alkohol sehr leicht löslich, schwer in  Äther.

   Sie schmilzt bei<B>172'</B> C und hat die  Neigung, Lösungsmittel festzuhalten, wo  durch der Schmelzpunkt\ leicht herunter  gedrückt wird. Sie lässt sich ohne Reiz  wirkung subkutan einspritzen und soll für  pharmazeutische Zwecke verwendet werden.       Beispiel:     Man löst 2,3 Gewichtsteile Natrium in  trockenem Sprit, fügt 16,7 Gewichtsteile  Kampf     eroxim    und     14    Gewichtsteile     Diäthyl-          aminoäthylchlorid    hinzu und kocht mehrere  Stunden auf dem Wasserbade, filtriert, ver  dampft die alkoholische Lauge, versetzt den  Rückstand mit Alkali,     äther¯t    aus, ver  dampft und destilliert.

   Der so erhaltene       Diäthylaminoäthylkampferoximäther    siedet  bei 14 mm bei 150 bis<B>160'.</B> Zur Her  stellung des Chlorhydrates neutralisiert man  den     Oximäther    mit alkoholischer Salzsäure  und fällt mit Äther. Das Chlorhydrat ist      in Wasser und Alkohol sehr leicht löslich,  schwer in Äther. Es schmilzt bei<B>172'.</B>  Das Salz hat die Neigung, Lösungsmittel       festzuhalten,    wodurch der Schmelzpunkt  leicht heruntergedrückt wird.



  Process for the preparation of the chlorohydrate of diethylaminoäthylkampferogimäthers. It has been found that technically valuable products can be obtained by converting Ald or Ietoximes into basic oxime ethers and their salts. In this way it is possible to obtain water-soluble substances which can be injected subcutaneously without irritation and which are therefore suitable for pharmaceutical purposes.

   The new bodies can be obtained using the methods known for the preparation of basic ethers, for example by reacting the salts of oximes with 3minoallryl halides.



  The present patent is a process for the preparation of the chlorohydrate of diethylaminoäthylkampferoximäthers, which is characterized in that camphor oxime is treated with diethylaminoethylating agents, for example with diethyl aminoethyl halide, and the base he obtained, the diethylaminoäthylkampfer- oxime ether, is converted into its chlorohydrate. The new compound is very easily soluble in water and alcohol, difficult in ether.

   It melts at <B> 172 '</B> C and has a tendency to hold on to solvents, where the melting point \ is pushed down slightly. It can be injected subcutaneously without irritation and is intended to be used for pharmaceutical purposes. Example: 2.3 parts by weight of sodium are dissolved in dry fuel, 16.7 parts by weight of combat eroxime and 14 parts by weight of diethylaminoethyl chloride are added and the mixture is boiled for several hours on the water bath, filtered, the alcoholic liquor is evaporated, the residue is treated with alkali and ether ¯t off, evaporated and distilled.

   The diethylaminoethyl camphor oxime ether obtained in this way boils at 14 mm at 150 to 160 '. To prepare the chlorohydrate, the oxime ether is neutralized with alcoholic hydrochloric acid and precipitated with ether. The chlorine hydrate is very easily soluble in water and alcohol, difficult in ether. It melts at <B> 172 '. </B> The salt has a tendency to hold onto solvents, which depresses the melting point slightly.
