Description
Verfahren zur Herstellung eines Kondensationsproduktes. Es wurde gefunden, dass wertvolle Kon densationsprodukte entstehen, wenn man Ver- bindungen, welche eine Dioxydiphenylmethan- gruppierung folgender Art enthalten
EMI0001.0006
wobei R Wasserstoff oder Alkyl- bezw. Acyl- gruppen und X die Methylen- oder Karbonyl- gruppe bedeuten,
mit Methylolamiden von Carbonsäuren kondensiert.
Die Kondensation verläuft gut in An wesenheit von Kondensationsmitteln, z. B. von Säuren, wie Salzsäure und Schwefelsäure, oder von Salzen, wie Zinkchlorid, oder von wasserentziehenden Mitteln, wie Phosphortri- chlorid oder Phosphoroxychlorid.
Die auf die beschriebene Weise herstell- baren Produkte können als Heilmittel, ins besondere als Abführmittel oder als Zwischen produkte zu solchen verwendet werden. Gegenstand des vorliegenden Patentes ist ein Verfahren zur Herstellung eines Konden sationsproduktes, welches dadurch gekenn zeichnet ist, dass man Caprylsäure-N-methylol- amid auf 3,3-Di-p-oxyphenyl-indolinon-2 der Formel
EMI0001.0029
bei Gegenwart eines Kondensationsmittels ein wirken lässt.
Das Produkt ist in Natronlauge löslich und gibt mit Ferricyankali violette bis blaue Farbreaktion: <I>Beispiel:</I> 40 g 3,3-Di-p-oxyphenyl-indolinon-2, 60 g Zinkchlorid, 120 g Eisessig werden heiss ge löst und nach dem Abkühlen mit<B>22-65</B> g Caprylsäure-N-metliylolamid versetzt, das sich leicht in dein CTemiscli auflöst. Nach 24stün- digem Stehen bei Zimmertemperatur wird die Lösung in dünnem Strahl in die Mischung von 2000 cm' Wasser und 100 cm" konzen trierter Salzsäure einfliessen gelassen.
Die körnige Masse wird abgesaugt, gut mit Was ser gewaschen und getrocknet. Durch Auf lösen in Methylalkohol und Eingiessen in eine 2'/2 /oige Sololösung kann das Produkt von unverändertem 3,3-Di-p-oxyplieny 1-indolinon-2 befreit werden.
Sollte es noch neutrale Pro dukte, zum Beispiel überschüssiges Capryl- säure-N-metliylolaniid enthalten, so kann es in 2000 cm'' 1 o,'oiger Natronlauge gelöst und zur Entfernung der neutralen Bestand teile klar filtriert und eventuell zweimal finit Äther ausgeschüttelt werden. Dann wird wie der in 1000 cm' Wasser und 50 eins kon zentrierte Salzsäure eingerührt, abgesaugt und mit Wasser gewaschen.
Die Verbindung löst sich leicht in 1 ;-"iger Natronlage. Die Lösung schäumt und gibt mit Ferricyankali eine violette bis blaue Farbreaktion.
Das Beispiel kann in der Weise abgeän dert werden, dass man statt Zinkchlorid-Eis- essig als Lösungs- und Kondensationsmittel andere Stoffe, zum Beispiel konzentrierte Schwefelsäure, verwendet.
Process for the production of a condensation product. It has been found that valuable condensation products are formed when compounds containing a dioxydiphenylmethane grouping of the following type are used
EMI0001.0006
where R is hydrogen or alkyl or. Acyl groups and X denotes the methylene or carbonyl group,
condensed with methylolamides of carboxylic acids.
The condensation goes well in the presence of condensing agents such. B. of acids such as hydrochloric acid and sulfuric acid, or of salts such as zinc chloride, or of dehydrating agents such as phosphorus trichloride or phosphorus oxychloride.
The products that can be manufactured in the manner described can be used as medicinal products, in particular as laxatives, or as intermediate products. The subject of the present patent is a process for the production of a condensation product which is characterized in that caprylic acid-N-methylolamide is added to 3,3-di-p-oxyphenyl-indolinone-2 of the formula
EMI0001.0029
in the presence of a condensing agent can act.
The product is soluble in sodium hydroxide solution and gives violet to blue color reactions with ferricyanide potassium: <I> Example: </I> 40 g of 3,3-di-p-oxyphenyl-indolinone-2, 60 g of zinc chloride, 120 g of glacial acetic acid become hot and after cooling down, <B> 22-65 </B> g of caprylic acid-N-methylolamide are added, which dissolves easily in your CTemiscli. After standing for 24 hours at room temperature, the solution is allowed to flow in a thin stream into the mixture of 2000 cm of water and 100 cm of concentrated hydrochloric acid.
The granular mass is filtered off with suction, washed well with water and dried. The product can be freed from the unchanged 3,3-di-p-oxyplieny 1-indolinone-2 by dissolving in methyl alcohol and pouring it into a 2½% strength solution.
Should it still contain neutral products, for example excess caprylic acid-N-methylolaniide, it can be dissolved in 2000 cm '' 10 '' sodium hydroxide solution and filtered to remove the neutral components and possibly shaken out twice with finite ether . Then like that in 1000 cm 'of water and 50 one concentrated hydrochloric acid is stirred in, filtered off with suction and washed with water.
The compound dissolves easily in a 1% sodium hydroxide layer. The solution foams and gives a violet to blue color reaction with ferricyankali.
The example can be modified in such a way that, instead of zinc chloride-glacial acetic acid, other substances, such as concentrated sulfuric acid, are used as solvents and condensation agents.
