Description
Verfahren zur Herstellung eines neuen basischen Äthers. Gegenstand des vorliegenden Patentes ist ein Verfahren zur Herstellung eines neuen basischen Äthers, nämlich des 1-(2',4',6'-Tri- methyl - phenoxy) - 2 - isopropylamino - propans, Es wurde gefunden, dass dieser Äther das vegetative Nervensystem beeinflusst. Er soll daher als Pharmazeutikum und als Zwischen produkt zur Herstellung weiterer Derivate Verwendung finden.
Das den Gegenstand des Patentes bildende Verfahren ist dadurch gekennzeichnet, dass man eine Verbindung der Formel
EMI0001.0010
unter reduzierenden Bedingungen mit einer Verbindung der Formel
EMI0001.0012
umsetzt; in welchen beiden Formeln eines der X ein Sauerstoffatom imd das andere ein Wasserstoffatom neben einem zur reduktiven Alkylierung befähigten und dabei die -NH- Gruppe ergebenden stickstoffhaltigen Rest bedeutet.
Man kann 'erfindungsgemäss beispielsweise 1- (2',4',6'-Trimethyl- phenoxy) - 2 - oxo - propan mit Isopr opylamin und einem Reduktionsmit tel zur Reaktion bringen. Man kann dabei so vorgehen, dass das Isopropylamin in Gegen wart des andern Ausgangsstoffes aus 2-Nitro- propan gebildet wird. Als Reduktionsmittel kann man die für solche Fälle üblichen, wie z. B. Zink -und Mineralsäuren, aktiviertes Alu minium usf., verwenden.
Als weitaus ergiebig stes Reduktionsmittels ist aber katalytisch er regter Wasserstoff anzusprechen. Als Kataly satoren -sind die Metalle der Raney-Gruppe, die bekannten Platin-Katalysatoren usf., ver wendbar. Wird in Gegenwart von Raney- Katalysator en reduziert, so arbeitet man vor zugsweise -unter Druck; beim Arbeiten in Ge genwart von Platin-Katalysatoren kann der Wasserstoff ohne Druck oder mit nur leich tem Überdruck angewendet werden. Die Re duktion wird vorteilhaft in einem Lösungsmit tel, beispielsweise in niederen Alkoholen, durchgeführt.
Man kann erfindungsgemäss auch 1-(2', 4',6'-Trimethyl-phenoxy)-2-amino-propan mit Aceton und einem Reduktionsmittel umsetzen. Dabei kann man das 1-(2',4',6'-Trimethyl- phenoxy )-2-amino-propan in Gegenwart des andern Ausgangsstoffes aus 1-(2',4',6'-Tri- methyl-phenoxy) -2-nitro-propan herstellen.
Eine weitere des Verfah rens besteht darin, dass man 1-(2',4',-6'-Tri- methyl-phenoxy )-2-oxo-propan mit N-Isopr o- pyl-benzylamin zusammen katalytisch redu ziert, wobei man zugleich die reduktive Alky- lierung und Debenzylierumg vornimmt.
Das so erhaltene 1-(2',4',6'-Trimetliyl-phen- oxy) -2-isopropylamino-propan siedet unter 1.2 mm bei 151-152 C und bildet ein farb loses Öl. Das Chlorhydrat der Verbindung schmilzt bei 168 C.
Der neue basische Äther soll als Zwischen- prodiLkt und als Pharmazeutikum Verwen- dtmg finden.
<I>Beispiel 1:</I> 40,0 g 1- (2',4',6'-Trimethyl-phenoxy) -2- oxo-propan -Lind 30,0 g Isopropylamin werden in 150 em3 Methanol gelöst und 10 Stunden im Autoklaven bei 20 C (120 atü) kataly tisch hydriert.
Als Katalysator wird Raney-Niekel ver wendet.
Der Katalysator wird abgenutseht, das Fil trat eingedampft, der Rückstand in 2n-Salz- säure aufgenommen und ausgeäthert. Aus der salzsauren Lösung wird mit konz. Natronlauge die Base in Freiheit gesetzt und in Äther auf genommen.
Nach dem Trocknen und Verdampfen des Äthers wird der Rückstand bei vermindertem Druck destilliert,twobei man das unter 12 mm bei<B>151-1520</B> C siedende 1-(2',4',6'-Trimethyl- phenoxy)-2-isopropyIamino-propan in 32,3- prozentiger Ausbeute gewinnt.
Das Chlorhydrat der Base schmilzt bei 168 C.
<I>B</I> eispiel <I>2:</I> 1 Mol 1-(2',4',6'-Trimethyl-plienoxy)-2-oxö- propan und 2,3 hfol 2-Nitro-propan werden in gleicher Weise wie unter Beispiel 1 angege ben zusammen reduziert. Man erhält so 1-(2', 4',6'-Trimethyl-phenoxy) - 2-isopropylamino- propan in befriedigender Ausbeute.
<I>Beispiel 3:</I> 1 Mol 1- (2',4',6'-Trimethyl-phenoxy) -2- amino-propan und 3 Mol Aceton werden in Gegenwart von Raney-Nickel bei 20 C (150 atü) hydriert. Die Aufarbeitung erfolgt gleich wie in Bei spiel 1.
Mann erhält so ebenfalls 1- (2',4',6'-Tri- methyl-phenoxy)-2-isopropyla.mino-propan in guter Ausbeute.
<I>Beispiel. 4:</I> 1 Mol 1-(2',4',6'-Trimethyl-phenoxy)-2-ni- tro-propan und 3 Mol Aceton werden unter den gleichen Bedingungen wie im Beispiel 3 beschrieben zusammen reduziert. Die Auf arbeitung erfolgt nach Beispiel 1. Man erhält 1- (2',4',6'-Trimethyl-phenoxy) -2-isopropyl- amino-propan in guter Ausbeute.
<I>Beispiel 5:</I> 1 Mol 1-(2',4',6'-Trimethyl-phenoxy)-2-oxo- propan und 1,5 Mol N-Isopropyl-benzylamin werden in Gegenwart von Raney-Nickel im Autoklaven bei 20 C (160 atü) hydriert. Die Aufarbeitung, die gleich wie in Beispiel 1 an gegeben erfolgen kann, liefert 1-(2',4',6'-Tri- methyl-phenoxy)-2-isopropylamino-propan in befriedigender Ausbeute.
Process for the production of a new basic ether. The subject of the present patent is a process for the production of a new basic ether, namely 1- (2 ', 4', 6'-trimethyl-phenoxy) -2-isopropylamino-propane. It was found that this ether is the vegetative Affects nervous system. It should therefore be used as a pharmaceutical and as an intermediate product for the production of further derivatives.
The method forming the subject of the patent is characterized in that a compound of the formula
EMI0001.0010
under reducing conditions with a compound of the formula
EMI0001.0012
implements; In which two formulas one of the X is an oxygen atom and the other is a hydrogen atom in addition to a nitrogen-containing radical capable of reductive alkylation and thereby giving the -NH- group.
According to the invention, for example, 1- (2 ', 4', 6'-trimethylphenoxy) - 2 - oxo - propane can be reacted with isopropylamine and a reducing agent. One can proceed in such a way that the isopropylamine is formed from 2-nitropropane in the presence of the other starting material. As a reducing agent, the usual for such cases, such. B. zinc and mineral acids, activated aluminum, etc., use.
By far the most productive reducing agent, however, is catalytically activated hydrogen. The metals of the Raney group, the known platinum catalysts, etc., can be used as catalysts. If reduction is carried out in the presence of Raney catalysts, it is preferably carried out under pressure; When working in the presence of platinum catalysts, the hydrogen can be used without pressure or with only a slight excess pressure. The reduction is advantageously carried out in a solvent, for example in lower alcohols.
According to the invention, 1- (2 ', 4', 6'-trimethylphenoxy) -2-aminopropane can also be reacted with acetone and a reducing agent. The 1- (2 ', 4', 6'-trimethylphenoxy) -2-aminopropane can be obtained in the presence of the other starting material from 1- (2 ', 4', 6'-trimethylphenoxy) Prepare -2-nitro-propane.
Another of the process is that 1- (2 ', 4', - 6'-trimethylphenoxy) -2-oxo-propane is reduced together catalytically with N-isopropyl-benzylamine, with reductive alkylation and debenzylation are carried out at the same time.
The 1- (2 ', 4', 6'-trimethylphenoxy) -2-isopropylamino-propane thus obtained boils below 1.2 mm at 151-152 ° C. and forms a colorless oil. The hydrochloride of the compound melts at 168 C.
The new basic ether is to be used as an intermediate product and as a pharmaceutical.
<I> Example 1: </I> 40.0 g of 1- (2 ', 4', 6'-trimethyl-phenoxy) -2-oxo-propane -Lind 30.0 g of isopropylamine are dissolved in 150 cubic meters of methanol and Hydrogenated catalyic table for 10 hours in an autoclave at 20 C (120 atmospheres).
Raney-Niekel is used as the catalyst.
The catalyst is removed, the filtrate is evaporated, the residue is taken up in 2N hydrochloric acid and extracted with ether. From the hydrochloric acid solution is made with conc. Caustic soda set the base free and taken up in ether.
After drying and evaporation of the ether, the residue is distilled under reduced pressure, with the 1- (2 ', 4', 6'-trimethylphenoxy) boiling below 12 mm at <B> 151-1520 </B> C -2-isopropylamino-propane wins in 32.3 percent yield.
The chlorohydrate of the base melts at 168 C.
<I> B </I> Example <I> 2: </I> 1 mol of 1- (2 ', 4', 6'-trimethyl-plienoxy) -2-oxo-propane and 2,3 hfol 2-nitro propane are reduced together in the same way as specified in Example 1. 1- (2 ', 4', 6'-trimethyl-phenoxy) -2-isopropylaminopropane is thus obtained in a satisfactory yield.
<I> Example 3: </I> 1 mol 1- (2 ', 4', 6'-trimethylphenoxy) -2-aminopropane and 3 mol acetone are in the presence of Raney nickel at 20 ° C (150 atü) hydrogenated. The processing is the same as in Example 1.
This also gives 1- (2 ', 4', 6'-trimethylphenoxy) -2-isopropyla.mino-propane in good yield.
<I> example. 4: 1 mol of 1- (2 ', 4', 6'-trimethyl-phenoxy) -2-nitro-propane and 3 mol of acetone are reduced together under the same conditions as described in Example 3. Working up is as in Example 1. 1- (2 ', 4', 6'-trimethylphenoxy) -2-isopropylamino propane is obtained in good yield.
<I> Example 5: </I> 1 mol 1- (2 ', 4', 6'-trimethylphenoxy) -2-oxopropane and 1.5 mol N-isopropylbenzylamine are in the presence of Raney Nickel hydrogenated in an autoclave at 20 ° C. (160 atm.). Working up, which can be carried out in the same way as in Example 1, gives 1- (2 ', 4', 6'-trimethylphenoxy) -2-isopropylamino-propane in satisfactory yield.
