50 die Unterdrückung der durch Pentamethylentetrazol erzeugten Krämpfe als auch die Todesfälle berücksichtigt wurden. Die akute Toxizität wurde an Gruppen von jeweils 10 Mäusen mit einem Gewicht von 20 ± 2 g in drei verschiedenen Dosen bestimmt. Die lethale Dosis wurde als die Dosis einer Verbindung bestimmt, die 50 Prozent der Tiere 10 Tage nach oraler Verabreichung der Verbindung tötete. Die Ergebnisse sind in der Tabelle zusammengestellt. 50 the suppression of convulsions produced by pentamethylenetetrazole as well as the deaths were taken into account. The acute toxicity was determined in groups of 10 mice each weighing 20 ± 2 g in three different doses. The lethal dose was determined as the dose of a compound which killed 50 percent of the animals 10 days after oral administration of the compound. The results are compiled in the table.
Aus der Tabelle ist ersichtlich, daß die Verbindungen der Erfindung den bekannten Verbindungen hinsichtlich ihrer höheren Antipentamethylentetrazol-Aktivität und/oder ihrer geringeren Toxizität überlegen sind. Die Beispiele erläutern die Erfindung.From the table it can be seen that the compounds of the invention with respect to the known compounds are superior to their higher antipentamethylene tetrazole activity and / or their lower toxicity. The examples illustrate the invention.
Eine Lösung von 0,5 g 2-(j3-Allyloxyäthyl-amino)-5-chlorbenzophenon in 50 ml wasserfreiem Methylenchlorid wird mit 1,0 g Oxazolidindion-(2,5) versetzt. Danach wird das Gemisch bei 5°C mit einer Lösung von Chlorwasserstoff in Äther versetzt und 5 Tage bei Raumtemperatur gerührt. Hierauf wird das Reaktionsgemisch in Wasser eingegossen, mit wäßriger Ammoniaklösung alkalisch gemacht und mehrmals mit Methylenchlorid extrahiert. Die vereinigten Methylenchl-ridextrakte werden über Natriumsulfat getrocknet, und das Lösungsmittel wird unter vermindertem Druck abdestilliert. Der Rückstand wird aus Isopropanol umkristallisiert.
