worin R gleiche oder verschiedene Alkylreste mit.
1 bis 4 Kohlenstoffatomen, insbesondere Methyl- oder Äthylreste, oder zwei R zusam men mit dem N-Atom einen 5- bis 6gliedrigen gesättigten heterocy clisclien Rest, wie den Pyr- rolidino-, Piperidino-, 2-Methyl-piperidino- oder Morpholinorest, und m und m' ganze Zahlen von 2 bis 4 bedeuten, sind bisher nicht bekanntgeworden.
Solche Verbindungen können als Ausgangs stoffe zur Herstellung von verschiedenartigen diquartären Diammoniumverbindüngen, wel che als Pharmazeutika zur Beeinflussung des lluskeltonus in Frage kommen, Verwendung finden.
Die neuen ditertiären Bis-aminoalkoxy- alkanekönnen beispielsweise durch Umsetzung des a,o.)-Alkandiols der Formel HO-(CH2 )10-0H vorteilhaft in Form seiner Metallverbindun gen (Alkoholate), mit 2 11T01 von tertiären :lminoalkylhalogeniden der Formel
EMI0001.0036
erhalten werden.
Dieses Verfahren eignet sich zum Beispiel für die Herstellung von diter- tiären Bis-(y-amino-propoxy)-alkanen.
Eine andere Möglichkeit besteht in der Umsetzung von a,w-Dihalogen-alkanen der Formel Hal-( CH2 ) io-Hal mit 2 Mol von Tertiäraminoalkoholen der

Formel
<tb> R
<tb> N-(CH2)m <SEP> OH
<tb> R vorteilhaft in Form ihrer Metallverbindungen (r11koholate). Bei der Herstellung von diter- tiären Bis-(8-amino-biitoxy)-alkanen hat sich dieses Verfahren als günstig erwiesen.
Indem man in obigen beiden Umsetzungen zunächst nur ein Mol eines tertiären Amino- alkylhalogenids bzw. Aminoalkohols verwen det und hierauf ein Mol einer analogen Ver bindung, kann man zu unsymmetrischen diter- tiären Basen [z. B. 1-(3-Diäthtlamino-but^ oxy)-10-(,B-dimethylamino-äthoxy)-dekan] ge langen.
Als tertiäre Aminoalkylhalogenide kommen zum Beispiel f-Chlor-äthyl- oder y-Brom-pro- pyl-dimethylamin, -methyläthylamin, -methyl- propy lamin, -methyl-butylamin, -methyl-iso- butylamin, -diäthylamin, -äthylpropyl-amin, -äthyl-butylamin, -äthyl-isobutyl-amin, -dipro- pylamin,
-propyl-butylamin, -propy 1-isobutyl- amin, -dibuty lamin, -butyl-isobutylamin, -di- isobutylamin, -metliyl-isopropylamin, -methyl- sec.butylamin, N-(ss-Chlor-äthyl)- oder N-(y- Brom-propyl) -pyrrolidin, -piperidin,
-\?-me- thyl-piperidin, -morpholin in Betracht.
Gegenstand vorliegenden Patentes ist nun ein Verfahren zur Herstellung eines Bis- aminoalkoxy-alkans. Das Verfahren ist da durch gekennzeichnet, dass man ein 1Tol einer Verbindung der Formel X,-(CH.)io-Xl mit zwei Mol eines Amins der Formel
EMI0002.0033
umsetzt, wobei von den Resten X1 und X@ der eine Halogen und der andere einen mit Ausnahme eines in ihm enthaltenen Sauer stoffatoms bei der Reaktion sieh abspaltenden Rest bedeutet.
Die erhaltene neue Verbindung, das 1,10- Bis-(fl-dimethylamino-äthoxy) -dekan, stellt eine farbloses Öl dar, das unter 0,04 mm Druck bei 131 bis 137 siedet. Sie soll als Zwi schenprodukt für die Herstellung von Arznei mittel dienen.
<I>Beispiel 1:</I> Zu 17,4 Teilen 1,10-Dekan-diol und 28 Tei len Dimethylaminoäthylclilorid in 100 Volum- teilen abs. Toluol werden bei 50 bis 60 10,5 Teile Natriumamid, welche zuvor durch Mah len in der Kugelmühle in 50 Volumteilen abs. Toluol suspendiert wurden, unter Rühren allmählich zugegeben. Darauf wird weitere Stunden bei 50 bis 60 und anschliessend 20 Stunden unter Kochen am Rückfloss wei tergerührt.
Nach dem Erkalten wird die ge bildete Base durch Verrühren mit überschüs siger 2n-Salzsäure in eine salzsaure Lösung übergeführt, diese mit Äther gewaschen, mit Tierkohle abgesaugt und unter Eiskühlung mit überschüssiger 30 % iger Natronlauge ver- setzt. Die Base wird ausgeäthert und, nach Trocknen der Ätherlösung mit Kalium- hy droxyd, durch fraktionierte Destillation im Hochvakuum gereinigt.
Das so erhaltene 1,10- Bis-(ss-dimethylamino-ätlioxy )-dekan ist ein farbloses Öl vom Siedepunkt 13-1 bis 137 un ter 0,01 mm Druck. Beispiel Ein Gemisch von 87 Teilen 1,10-Dekandiol,
172 Teilen Dimethyiaminoä.thylclilorid-hydro- ehlorid und 100 Volumteilen abs. Toluol wird bei 90 bis 100 unter Rühren mit einer fein gemahlenen Suspension von 58 Teilen Na- triumhvdrid in 250 Volumteilen abs. Toluol in kleinen Portionen versetzt. Hierauf kocht man 14 Stunden unter Rückfloss und arbeitet nach dem Erkalten auf, wie in Beispiel 1 an gegeben.

wherein R has identical or different alkyl radicals.
1 to 4 carbon atoms, especially methyl or ethyl radicals, or two R together with the N atom a 5- to 6-membered saturated heterocyclic radical, such as the pyrrolidino, piperidino, 2-methyl-piperidino or morpholino radical, and m and m 'mean integers from 2 to 4 have not yet become known.
Such compounds can be used as starting materials for the production of various types of diquartar diammonium compounds which can be used as pharmaceuticals for influencing the muscle tone.
The new ditertiary bis-aminoalkoxyalkanes can, for example, by reaction of the a, o.) -Alkanediol of the formula HO- (CH2) 10-0H, advantageously in the form of its metal compounds (alcoholates), with 2 11T01 of tertiary: iminoalkyl halides of the formula
EMI0001.0036
can be obtained.
This process is suitable, for example, for the production of di-tertiary bis (γ-aminopropoxy) alkanes.
Another possibility is to react a, w-dihaloalkanes of the formula Hal- (CH2) io-Hal with 2 mol of tertiary amino alcohols

formula
<tb> R
<tb> N- (CH2) m <SEP> OH
<tb> R advantageously in the form of their metal compounds (alcoholates). This process has proven to be beneficial in the preparation of diter- tiary bis (8-aminobiitoxy) alkanes.
By initially using only one mole of a tertiary amino alkyl halide or amino alcohol and then one mole of an analogous compound in the above two reactions, unsymmetrical diter- tiary bases [e.g. B. 1- (3-diethylamino-but ^ oxy) -10 - (, B-dimethylamino-ethoxy) -dekan] ge long.
Examples of tertiary aminoalkyl halides are f-chloro-ethyl or y-bromopropyl-dimethylamine, -methylethylamine, -methylpropylamine, -methyl-butylamine, -methyl-isobutylamine, -diethylamine, -äthylpropyl- amine, -ethyl-butylamine, -ethyl-isobutyl-amine, -dipropylamine,
-propyl-butylamine, -propy 1-isobutylamine, -dibuty lamin, -butyl-isobutylamine, -diisobutylamine, -metliyl-isopropylamine, -methyl-sec.butylamine, N- (ss-chloro-ethyl) - or N- (y-bromo-propyl) -pyrrolidine, -piperidine,
- \? - methyl piperidine, morpholine into consideration.
The present patent now relates to a process for the preparation of a bis-aminoalkoxy-alkane. The process is characterized in that one tol of a compound of the formula X, - (CH.) Io-Xl with two moles of an amine of the formula
EMI0002.0033
converts, where of the radicals X1 and X @ one is halogen and the other one with the exception of an oxygen atom contained in it is a radical which is split off during the reaction.
The new compound obtained, the 1,10-bis- (fl-dimethylamino-ethoxy) -dekan, is a colorless oil which boils at 131-137 under 0.04 mm pressure. It should serve as an intermediate product for the manufacture of pharmaceuticals.
<I> Example 1 </I> To 17.4 parts of 1,10-decanediol and 28 parts of dimethylaminoethyl chloride in 100 parts by volume of abs. Toluene at 50 to 60 10.5 parts of sodium amide, which was previously abs by Mah len in the ball mill in 50 parts by volume. Toluene were suspended, gradually added with stirring. The mixture is then stirred for a further 50 to 60 hours and then for 20 hours while refluxing.
After cooling, the base formed is converted into a hydrochloric acid solution by stirring with excess 2N hydrochloric acid, this is washed with ether, suctioned off with animal charcoal and treated with excess 30% sodium hydroxide solution while cooling with ice. The base is extracted with ether and, after drying the ethereal solution with potassium hydroxide, purified by fractional distillation in a high vacuum.
The 1,10-bis- (ss-dimethylamino-ätlioxy) -dekan thus obtained is a colorless oil with a boiling point of 13-1 to 137 under 0.01 mm pressure. Example A mixture of 87 parts of 1,10-decanediol,
172 parts of Dimethyiaminoä.thylclilorid-hydro ehlorid and 100 parts by volume of abs. Toluene is at 90 to 100 with stirring with a finely ground suspension of 58 parts of sodium hydride in 250 parts by volume of abs. Toluene added in small portions. It is then refluxed for 14 hours and worked up after cooling, as given in Example 1.
