Description

Verfahren zur Herstellung von tertiären, einen Oxazolidonylrest enthaltenden Aminen Es wurde gefunden, daß man tertiäre Amine erhält, wenn man cyclische Urethane mit Formaldehyd und Verbindungen, die mindestens eine sekundäre basisch reagierende Aminogruppe enthalten, umsetzt. Die Reaktion verläuft z. B. bei Umsetzung von Oxazolidon- (2) mit Formaldehyd und Dimethylamin nach folgendem Schema: unter Bildung von Dimethyl-oxazolidonylmethylamin. Weitere für das Verfahren geeignete Verbindungen mit mindestens einer sekundären Aminogruppe sind z. B. Diäthylamin, Methyläthylamin, Dibutylamin, Pyrrolidin, Piperidin, Piperazin oder Morpholin.Process for the preparation of tertiary amines containing an oxazolidonyl radical It has been found that tertiary amines are obtained when cyclic urethanes are reacted with formaldehyde and compounds which contain at least one secondary amino group with a basic reaction. The reaction proceeds z. B. when reacting oxazolidone- (2) with formaldehyde and dimethylamine according to the following scheme: with formation of dimethyl-oxazolidonylmethylamine. Further compounds having at least one secondary amino group which are suitable for the process are, for. B. diethylamine, methylethylamine, dibutylamine, pyrrolidine, piperidine, piperazine or morpholine.

Die Umsetzung wird zweckmäßig bei Raumtemperatur durchgeführt, und es ist vorteilhaft, bei der verhältnismäßig heftig verlaufender exothermen Reaktion zu kühlen. :Ulan kann das Verfahren so durchführen, daß man alle Reaktionsteilnehmer mischt; es ist aber auch möglich, zunächst den Formaldehyd mit dem cyclischen Urethan oder mit dem sekundären Amin umzusetzen und dann erst die dritte Reaktionskomponente hinzuzufügen.The reaction is expediently carried out at room temperature, and it is beneficial at the proportionate more violent to cool exothermic reaction. : Ulan can carry out the procedure in such a way that one mixes all reactants; but it is also possible to first use the formaldehyde to react with the cyclic urethane or with the secondary amine and only then add the third reaction component.

Die neuen tertiären Amine stellen, insbesondere in Form ihrer quaternären Ammoniumverbindungen, die sich z. B. durch Umsetzung mit Benzylchlorid herstellen lassen, wertvolle Zwischenprodukte für die Herstellung von Heilmitteln dar.The new tertiary amines represent, especially in the form of their quaternary Ammonium compounds that are z. B. produce by reaction with benzyl chloride are valuable intermediate products for the manufacture of medicinal products.

Die in den nachstehenden Beispielen angegebenen Teile sind Gewichtsteile.The parts given in the examples below are parts by weight.

Beispiel i 87 Teile Oxazolidon-(2), iio Teile 3op/pige wäßrige Formaldehydlösung und i3o Teile Dibutylamin werden unter lebhaftem Rühren gemischt. Die Umsetzung beginnt sofort; zur Abführung der Reaktionswärme wird mit Wasser von Raumtemperatur gekühlt. Nach etwa 4 Stunden ist die Reaktion beendet. Nach Abdestillieren des Wassers und der nicht umgesetzten flüchtigen Anteile geht bei 13o bis 132°p,4 Torr das Dibutyl-oxazolidonylmethyl-amin über. Man erhält 184 Teile dieses tertiären Amins.Example i 87 parts of oxazolidone (2), iio parts of 3 op / pige aqueous formaldehyde solution and 13o parts of dibutylamine are mixed with vigorous stirring. The implementation starts immediately; to dissipate the heat of reaction, water at room temperature is used chilled. The reaction has ended after about 4 hours. After distilling off the water and of the unconverted volatile components, the dibutyl-oxazolidonylmethyl-amine goes at 130 to 132 ° p.4 Torr above. 184 parts of this tertiary amine are obtained.

Beispiel 2 87 Teile Oxazolidon-(2), iio Teile 3op/pige wäßrige Formaldehydlösung und 1i2 Teile einer 4oo/pigen wäBrigen Lösung von Dimethylamin werden wie im Beispiel i umgesetzt. Man erhält 118 Teile Dimethyloxazolidonylmethyl-amin, das bei 90'p,2 Tor, übergeht. Beispiel 3 87 Teile Oxazolidon-(2) werden mit ioo Teilen 3oo/piger Formaldehydlösung versetzt und 24 Stunden bei Raumtemperatur stehengelassen. Es bildet sich die N-Methylolverbindung des Oxazolidons, was an der Abnahme der Aldehydkonzentration leicht festzustellen ist. Dann wird die Lösung mit 73 Teilen Diäthylamin versetzt und erneut 24 Stunden stehengelassen. Die weitere Aufarbeitung erfolgt wie im Beispiel i. Man erhält 138 Teile Diäthyl-oxazolidonylmethylamin (Kpo,2 Torr = I07°).Example 2 87 parts of oxazolidone (2), iio parts of 3 op / pige aqueous formaldehyde solution and 1 1/2 parts of a 400 per cent aqueous solution of dimethylamine are as in the example i implemented. 118 parts of dimethyloxazolidonylmethylamine are obtained, which at 90'p, 2 Gate, passes. Example 3 87 parts of oxazolidone- (2) are mixed with 100 parts of 300 / piger Formaldehyde solution is added and the mixture is left to stand at room temperature for 24 hours. It the N-methylol compound of the oxazolidone is formed, which is due to the decrease in the aldehyde concentration is easy to determine. 73 parts of diethylamine are then added to the solution and left to stand again for 24 hours. The further work-up takes place as in the example i. 138 parts of diethyl oxazolidonylmethylamine (Kpo, 2 Torr = 107 °) are obtained.

Beispiel 4 7i Teile Pyrrolidin werden unter Kühlen mit ioo Teilen 3op/piger Formaldehydlösung versetzt und über Nacht stehengelassen. Danach werden 87 Teile Oxazolidon-(2) hinzugefügt, es wird 2 Stunden auf 8o' erwärmt und das Produkt nun im Vakuum von Wasser befreit. Der Rückstand wird im Vakuum destilliert; man erhält 128 Teile Oxazolidon-(2)-yl-(3) -pyrrolidino-methan (Kpo,2 Tor, = i23').Example 4 7i parts of pyrrolidine are added to 100 parts with cooling 3op / piger formaldehyde solution was added and left to stand overnight. After that will be 87 parts of oxazolidone- (2) are added, the mixture is heated to 80 'for 2 hours and the product now freed from water in a vacuum. The residue is distilled in vacuo; man receives 128 parts of oxazolidone- (2) -yl- (3) -pyrrolidino-methane (Kpo, 2 Tor, = i23 ').
