Description
<Desc/Clms Page number 1>
Verfahren zur Darstellung von Hexamethylentetraminsalzen der a-Phenylchinolin- - r -karbon8äuren.
Es wurde gefunden, dass man durch Vereinigung von Hexamethylentetramin mit N-Phenylchinolin-Y-karbonsäuro oder deren Derivaten zu Verbindungen gelangt, die für medizinische Zwecke wertvoll sind. Um die neuen Verbindungen darzustellen, bringt man die genannten Karbonsäuren mit der äquimolekularen Menge Hexamethylentetramin in einem geeigneten Lösungsmittel zusammen und kann dann die neue Verbindung entweder durch Kristallisation oder Fällung aus der Lösung abscheiden.
Beispiel : 70 Teile Hexamethylentetramin werden mit der 15fachen Menge absoluten Alkohols gekocht und 125 Teile α-Phenylchinolin-γ-karbonsäure hinzugegeben. Es entsteht dann eine Lösung, aus welcher die neue Verbindung < x-phenylchinolin-Y-karbon- saures Hexamothylentetramin beim Erkalten kristallisiert. Sie bildet kleine Kristalle, die in Wasser und heissem Alkohol löslich, in Äther unlöslich sind und deren Schmelz- und Zersetzungspunkt bei etwa 1850 liegt. In gleicher Weise kann z. B. α-Phenylchininsäure zur Darstellung einer analogen Verbindung verwendet werden.

Process for the preparation of hexamethylenetetramine salts of a-phenylquinoline - r -carboxylic acids.
It has been found that the combination of hexamethylenetetramine with N-phenylquinoline-Y-carboxylic acid or derivatives thereof leads to compounds which are valuable for medical purposes. To produce the new compounds, the carboxylic acids mentioned are combined with the equimolecular amount of hexamethylenetetramine in a suitable solvent and the new compound can then be separated out from the solution either by crystallization or precipitation.
Example: 70 parts of hexamethylenetetramine are boiled with 15 times the amount of absolute alcohol and 125 parts of α-phenylquinoline-γ-carboxylic acid are added. A solution is then formed from which the new compound <x-phenylquinoline-Y-carbonic acid hexamothylenetetramine crystallizes on cooling. It forms small crystals that are soluble in water and hot alcohol, insoluble in ether and whose melting and decomposition point is around 1850. In the same way, for. B. α-phenylquinic acid can be used to prepare an analogous compound.
