Description

Verfahren zur Herstellung von in der .Amidgruppe substituierten Carbonsäureamiden Es ist bekannt, daß beim Erhitzen von Salzen aus niederen Fettsäuren und Ammoniak oder Aminen die entsprechenden Säureamide gebildet werden. Eine Umsetzung von Carbonsäureamiden mit solchen primären oder sekundären Aminen, die mindestens einen höhermolekularen Rest im Molekül enthalten, ist bisher noch nicht beschrieben worden, insbesondere noch nicht bei Aminocarbonsäureamiden.Process for the preparation of carboxamides substituted in the amide group It is known that when salts of lower fatty acids and ammonia are heated or amines, the corresponding acid amides are formed. A conversion of carboxamides with those primary or secondary amines that have at least one higher molecular weight Remainder contained in the molecule has not yet been described, in particular not yet with aminocarboxamides.

Es wurde nun gefunden., daß man zu technisch sehr wertvollen Verbindungen gelangt; wenn man die Salze aus, Carbonsäuren oder Aminocarbonsäuren und flüchtigen Basen mit solchen primären oder sekundären Aminen, die mindestens einen höhermolekularen Rest enthalten, umsetzt. Hierfür sind die Salze von Fettsäuren, aromatischen, alicyclischen oder heterocyclischen Carbonsäuren und überraschenderweise mit guter Ausbeute auch die Salze von am Stickstoff unsubstituierten oder substituierten Aminocarbonsäuren, z. B. von Aminoessigsäure, Dimethylaminoessigsäure, Aminopropionsäure, ß-Dimethylamino-a-diäthylpropionsäure, Diäthylaminobttttersäure, geeignet. Zur Salzbildung mit diesen Säuren eignen sich außer Ammoniak alle organischen Basen, die unter gewöhnlichem oder vermindertem Druck eine genügende Flüchtigkeit aufweisen, so z. B. Methylamin, Diäthylamin, Trimethylamin, Cyclohexylamin, N, N-Dimethylcyclohexylamin, Piperidin u. dgl.It has now been found that technically very valuable compounds can be obtained got; when you get the salts from, carboxylic acids or aminocarboxylic acids and volatile Bases with those primary or secondary amines that have at least one higher molecular weight Rest included, implements. For this are the salts of fatty acids, aromatic, alicyclic or heterocyclic carboxylic acids and, surprisingly, with good yield as well the salts of aminocarboxylic acids which are unsubstituted or substituted on the nitrogen, z. B. of aminoacetic acid, dimethylaminoacetic acid, aminopropionic acid, ß-dimethylamino-a-diethylpropionic acid, Diethylamino butter acid, suitable. These acids are suitable for salt formation except ammonia all organic bases under ordinary or have sufficient volatility under reduced pressure, e.g. B. methylamine, diethylamine, Trimethylamine, cyclohexylamine, N, N-dimethylcyclohexylamine, piperidine and the like.

Für die Umsetzung der Salze von Carbonsäüren bzw. Aminocarbonsäuren und flüchtigen Basen mit mindestens einen höhermolekularen Rest im Molekül enthaltenden primären oder sekundären Aminen kommen Octylamin, Decylamin, Undecylamin, Dodecylamin, Cetylamin, Octadecylamin, Octadecylmonomethylamin, Naphthenylamin, Benzylamin, p-Aminobenzyldodecylsulfid, p-Dodecoxyanilin, Cyclohexylamin und seine Homologen u. a. in Betracht.For the implementation of the salts of carboxylic acids or aminocarboxylic acids and volatile bases with at least one higher molecular weight residue in the molecule primary or secondary amines come octylamine, decylamine, undecylamine, dodecylamine, Cetylamine, octadecylamine, octadecylmonomethylamine, naphthenylamine, benzylamine, p-aminobenzyldodecyl sulfide, p-dodecoxyaniline, cyclohexylamine and its homologues, inter alia. into consideration.

Als besonders vorteilhaft hat sich das beschriebene Verfahren für die Umnsetzung des bei der Einwirkung von Monohalogenessigsäure, z. B. Monochloressigsäure, auf Piperidin erhältlichen Piperidinsalzes der Piperidinoessigsäure mit einem höhermolekularen Amins z. B. Dodecylamin, erwiesen, weil man auf diese Weise in glatter Reaktion zu Ausgangsstoffen für hochwirksame Desinfektionsmittel gelangt.The method described has proven to be particularly advantageous for the implementation of the action of monohaloacetic acid, z. B. monochloroacetic acid, Piperidine salt of piperidinoacetic acid available on piperidine with a higher molecular weight Amine z. B. Dodecylamine, proven to work this way in smoother response reaches raw materials for highly effective disinfectants.

Gegenüber der bekannten Darstellung von Acetamid aus essigsaurem Ammonium, welche nur mit ganz ungenügender Ausbeute durchführbar ist, verläuft dieUmsetzung vonhöhermolekularenprimären oder sekundären Aminen mit den Salzen von Carbonsäuren oder Aminocarbonsäuren mit sehr guter Ausbeute. Außerdem ist es nicht erforderlich, die höhermolekularen primären oder sekundären Amine in Salze der Aminocarbonsäuren Überzuführen. Es genügt vielmehr, dieselben mit den Salzen von flüchtigen Basen und Carbonsäuren auf höhere Temperatur zu erhitzen und durch Anwendung von Vakuum oder Durchleiten eines indifferenten Gasstromes die Abtrennung der flüchtigen Base sowie des gebildeten Wassers zu begünstigen. Die Reaktionstemperaturen, welche für die Durchführung der Umsetzung erforderlich sind, sind je nach den Arbeitsbedingungen und denn Molekulargewicht der umzusetzenden Stoffe verschieden. Sie liegen zwischen 8o und 30ö°, vornehmlich bei 15o bis 25d°`. Die erhältlichen Carbonsäureamide finden als Zwischenprodukte für die Herstellung pharmazeutisch wichtiger Präparate Verwendung.Compared to the well-known representation of acetamide from ammonium acetic acid, which can only be carried out with a very inadequate yield, the implementation proceeds of higher molecular weight primary or secondary amines with the salts of carboxylic acids or aminocarboxylic acids in very good yield. In addition, it is not necessary the higher molecular weight primary or secondary amines in salts of aminocarboxylic acids Transfer. Rather, it suffices to do the same with the salts of volatile bases and to heat carboxylic acids to a higher temperature and by applying vacuum or passing through an inert gas stream, the separation of the volatile base as well as the water formed. The reaction temperatures which for carrying out the implementation are required depending on the working conditions and because the molecular weight of the substances to be converted is different. They lie between 8o and 30ö °, mainly at 15o to 25d ° `. Find the available carboxamides Use as intermediate products in the manufacture of pharmaceutically important preparations.

Beispiel Zu 255 Gewichtsteilen Piperidin werden unter Rühren und Kühlen 9-,5 Gewichtsteile Chloressigsäure so zugegeben, daß die Temperatur nicht über 5ö° steigt. Nachdem einige Stunden auf 8o° erwärmt worden ist, werden 37o Gewichtsteile Dodecylamin; zugegeben. Unter Durchleiten eines Stickstoffstromes wird die Temperatur langsam bis auf 2o0,°' gesteigert, wobei Piperidin und Wasser abdestillieren. Sobald bei 2od°4 die Abspaltung des Wassers beendet ist, wird auf 8d°- abgekühlt und qo Gewichtsteile Ätznatron, gelöst in 8o Gewichtsteilen Wasser; eingerührt, die wäßrige Schicht abgetrennt und dann das überschüssige Dodecylamin im Vakuum abdestilliert. Aus dem bräunlich gefärbten Destillationsrückstand erhält man durch Umkristallisieren aus Petroläther in einer Ausbeute von über go% das Dodecylamid der Piperidinoessigsäure in ,reiner Form (Fp. ¢6 bis #') .Example To 255 parts by weight of piperidine are added with stirring and cooling 9.5 parts by weight of chloroacetic acid are added so that the temperature does not exceed 50 ° increases. After a few hours of heating to 80 °, it becomes 37o parts by weight Dodecylamine; admitted. The temperature is increased while a stream of nitrogen is passed through slowly increased to 2o0, ° ', with piperidine and water distilling off. As soon at 2od ° 4 the splitting off of the water is complete, it is cooled to 8d ° - and qo Parts by weight of caustic soda dissolved in 80 parts by weight of water; stirred in, the aqueous Layer separated and then the excess dodecylamine was distilled off in vacuo. The brownish colored distillation residue is obtained by recrystallization from petroleum ether in a yield of over go% the dodecylamide of piperidinoacetic acid in, pure form (mp. 6 to # ').
