Description
Verfahren zur Herstellung eines Tetrazol-Abkömmlings der Terpenreihe. Es ist bereits bekannt, dass man durch Behandlung von Carbonylverbindungen mit Stickstoffwasserstoffsäure in Gegenwart von Katalysatoren allgemein zu Tetrazolen ge langt.
Es wurde nun gefunden, dass man, aus gehend von Thujon, nach diesem Verfahren ein neues Tetrazol der Formel C10H16N4 er hält, welches eine analeptische Wirkung be sitzt, die stärker ist und länger anhält, als die des bekannten Pentamethylentetrazols. Vom Thujon unterscheidet sich dieser Stoff besonders durch seine erheblich grössere Lös lichkeit in Wasser.
Ausgehend vom reinen Thujon erhält man den Stoff als weissen, kristallinen Kör per vom Schmelzpunkt 91-92 0. Er ist in Wasser löslich, besser noch in den gebräuch lichen organischen Lösungsmitteln. Das Thu- jon des Handels liefert nach dem gleichen Verfahren ein Produkt, welches zunächst den Schmelzpunkt 86 0 besitzt. Das Ver fahrensprodukt kann für pharmazeutische Zwecke Verwendung finden.
<I>Beispiel:</I> Eine benzolische Lösung, enthaltend 0,2 112o1 Stickstoffwasserstoffsäure, 100 g Zinn tetrachlorid als Katalysator und etwa 10 g konzentrierte Schwefelsäure, wird unter Rüh ren mit einer Lösung von 30,4 g Thujon in Benzol versetzt. Die Ausbeute an Thujon- Tetrazol beträgt mehr als 70 % der Theorie.
Process for the preparation of a tetrazole derivative of the terpene series. It is already known that treatment of carbonyl compounds with hydrazoic acid in the presence of catalysts generally gives tetrazoles.
It has now been found that, starting from thujone, according to this method, a new tetrazole of the formula C10H16N4 is found, which has an analeptic effect that is stronger and lasts longer than that of the known pentamethylenetetrazole. This substance differs from thujone in particular in that it is considerably more soluble in water.
Based on pure thujone, the substance is obtained as a white, crystalline body with a melting point of 91-92 0. It is soluble in water, better still in common organic solvents. The thuion of the trade supplies a product which initially has a melting point of 86 0 using the same process. The process product can be used for pharmaceutical purposes.
<I> Example: </I> A benzene solution containing 0.2 112o1 hydrazoic acid, 100 g tin tetrachloride as catalyst and about 10 g concentrated sulfuric acid is mixed with a solution of 30.4 g thujone in benzene while stirring. The yield of thujone tetrazole is more than 70% of theory.
