Description
Verfahren zur Darstellung von Tropasäurebenzolamid. In den letzten Jahren ist das Bedürfnis nach einem kräftig wirkenden Cholereticum immer fühlbarer geworden, da es sich gezeigt hat, dass durch die gesteigerte Sekretion von Galle Krankheiten der Leber und der Gal lengänge günstig beeinflusst werden können. Bereits sind auch eine grössere Zahl von gal lentreibenden Präparaten in den Handel ge kommen. Die bekannteren davon enthalten als wirksame Bestandteile Gallensäureab- kömmlinge, Po,dophyllin, sowie Pflanzen extrakte (z. B. Rettichextrakt).
Weiter wur den schon Extrakte aus Leber und Gallen blasen als Choleretica verwendet.
Als Verbindungen mit einer .starken gal- lensekretionssteigernden Wirkung haben sich ,die neutralen N-substituierten Abkömmlinge des Tropasäureamids erwiesen.
Zur Herstel lung der neutralen N-,substituierten Abkömm linge des Tro.pasäureamids .lässt man auf 0-Acetyltropasäurechlorid aliphatische und aromatische primäre und sekundäre Amine, Piperidin und seine C-Substitutionsabkömm-- liege, Ara'lkylamine, Cycloalkylamine, ein wirken.
Zweckmässig werden die benützten Amine in wässeriger Lösung oder in einem organischen Lösungsmittel gelöst angewen- ,det. Aus, den erhaltenen, in der Amido- gruppe substituierten 0-Acetyltropasäure- amiden wird die Acetylgruppe durch Be handlung mit Alkalien oder Säuren abge spalten.
Gegenstand des vorliegenden Patentes ist ein Verfahren zur Darstellung von Tropa- säurebenzylamid, welches dadurch gekenn zeichnet ist, dass man Benzylamin auf 0-Acetyltropasäurechlorid einwirken lässt und aus dem entstandenen 0-Acetyltropa- s.äurebenzylamid die Acetylgruppe durch Säuren; oder Alkalien abspaltet.
Das bisher unbekannte Tropa säurebenzyl- amid schmilzt bei 124'. Es; löst sich in den meisten organischen Lösungsmitteln, in Wasser ist es schwer löslich. Mit Rücksicht auf seine gallensekretionssteigerndeWirkung soll es als Arzneimittel Verwendung finden.
Beispiel: 25 Teile 0-Acetyltropasäurechlorid löst man in 100 Teilen Toluol und lässt die Lö sung unter Kühlung zu einer Lösung von 35 Teilen Benzylamin in 300 Teilen Toluol zutropfen. Nach Extraktion mit Wasser und verdünnter Säure sowie Verdampfen des Toluols im Vakuum bleiben 41 Teile 0- Ace- tyltropasäurebenzylamid vom Schmelzpunkt 83 zurück.
Durch Lösen in 100 Teilen Alkohol und Zugabe der berechneten Menge 20%iger wässeriger Natronlauge bei etwa 40' wird die Acetylgruppe abgespalten. Das Tropasäurebenzylamid wird durch Ver dampfen der Lösung oder durch Zugabe von Wasser gewonnen. Durch Kristallisation aus Benzol erhält man es rein mit dem Schmelzpunkt 124'.
Process for the preparation of tropic acid benzolamide. In recent years the need for a powerful choleretic has become more and more palpable, as it has been shown that diseases of the liver and the biliary ducts can be favorably influenced by the increased secretion of bile. A large number of gall-driving preparations have already come onto the market. The more well-known of these contain bile acid derivatives, po, dophyllin and plant extracts (eg radish extract) as active ingredients.
Extracts from liver and gall bladders have also been used as choleretics.
The neutral N-substituted derivatives of tropic acid amide have proven to be compounds with a strong bile secretion-increasing effect.
To produce the neutral N-, substituted derivatives of tro.pasamides, aliphatic and aromatic primary and secondary amines, piperidine and its C-substitution derivatives, ara'lkylamines, cycloalkylamines are allowed to act on O-acetyltropic acid chloride.
The amines used are expediently applied in aqueous solution or dissolved in an organic solvent. The acetyl group is split off from the 0-acetyltropaic acid amides which are substituted in the amido group by treatment with alkalis or acids.
The subject of the present patent is a process for the preparation of tropa acid benzylamide, which is characterized in that benzylamine is allowed to act on 0-acetyltropic acid chloride and the acetyl group is formed from the resulting 0-acetyltropa acid benzylamide with acids; or splits off alkalis.
The previously unknown tropa acid benzylamide melts at 124 '. It; dissolves in most organic solvents, but is sparingly soluble in water. In view of its bile secretion-increasing effect, it should be used as a medicinal product.
Example: 25 parts of 0-acetyltropic acid chloride are dissolved in 100 parts of toluene and the solution is added dropwise with cooling to a solution of 35 parts of benzylamine in 300 parts of toluene. After extraction with water and dilute acid and evaporation of the toluene in vacuo, 41 parts of 0-acetyltropaic acid benzylamide with a melting point of 83 remain.
The acetyl group is split off by dissolving in 100 parts of alcohol and adding the calculated amount of 20% strength aqueous sodium hydroxide solution at about 40 '. The tropic acid benzylamide is obtained by evaporating the solution or by adding water. Crystallization from benzene gives it pure form with a melting point of 124 '.
