Ea wird dabei ao vorgegangen, dass Undecilensäure in Tetrahydrofuran gelöst und unter Rühren mit der Lösung von N, N'Ea the procedure ao is that undecilenic acid in Tetrahydrofuran dissolved and with stirring with the solution of N, N ' - Dioyclohexylcarbodiimid in Tetrahydrofuran versetzt wird. Danach wird 10 Minuten weitergerührt und dann unter weiterem Rühren Natrium- oder Kaliumsalz der 6-APS, gelöst in einem Gemisch Tetrahydrofuran-Wasser, im Verhältnis 1 : 1 langsam zugegeben. Das Reaktionsgemisch wird bei Raumtemperatur 2 Stunden weitergerührt und mit Wasser versetzt, um die Löslichkeit des bei der Reaktion entstandenen N, N"»Dicyclohezylharnstoffes zu vermindern. Der ausgeschiedene M, N'-Dicyclohexylharnstoff wird abfiltriert und das Filtrat im Alkalischen mit Aether ausgeschüttet, um die nicht-umgesetzten Ausgangsstoffe zu entfernen. Dann wird das Filtrat mit Aether überschichtet und mit verdünnter Schwefelsäure bis zu einem pH-Wert von 2 angesäuert. Nach der Trennung wird die wässrige Schicht noch zweimal mit Aether extrahiert. Die vereinigten Aet tierextrakt β, welche das 9-Decenylpenicillin in Form freier Säure enthalten, werden mit Wasser ausgewaschen und mit wässriger Natriumbicarbonatlösung auage schüttelt. Aus der wässrigen Lösung, welche das Natriumsalz des 9 - Decenyl-penicilline enthält, wird das rohe Natriumsalz durch Lyophilisation erhalten. Aus dem Natriumsalz wird auf bereits bekannte Weise das N, N* - Dibenzyläthylendiaminsalz des neuen Penicillins hergestellt.- Dioyclohexylcarbodiimide in tetrahydrofuran is added. The mixture is then stirred for a further 10 minutes and then, with further stirring, the sodium or potassium salt of 6-APS, dissolved in a mixture Tetrahydrofuran-water, added slowly in a ratio of 1: 1. The reaction mixture is stirred for a further 2 hours at room temperature and water is added to reduce the solubility of the The N, N'-dicyclohexylurea which has formed in the reaction is to be reduced. The M, N'-dicyclohexylurea which has separated out is filtered off and the filtrate is poured out in an alkaline solution with ether in order to remove the unreacted starting materials the filtrate is covered with ether and acidified with dilute sulfuric acid to a pH of 2. After Separation, the aqueous layer is extracted twice more with ether. The combined animal extract β, which contain the 9-decenylpenicillin in the form of free acid, are mixed with water Washed out and auage with aqueous sodium bicarbonate solution shakes. From the aqueous solution, which contains the sodium salt of 9-decenyl-penicillin, the crude sodium salt is made through Receive lyophilization. The sodium salt becomes on already known way the N, N * - dibenzylethylenediamine salt of the new Penicillins made.

Das neue Penicillin sowie sein Natrium- und N, N"» Dibensyläthylendiamlnsals sind gegen Staphylococcus aureus wirksam. Das rohe NatriumsalB ist in Wasser gut löslich und inhibiert das Wachstum von Staphylococcus aureus bei einer Konsentration von 1,2 Gamma/ml.The new penicillin and its sodium and N, N "» Dibensyläthylendiaminsals are against Staphylococcus aureus effective. The raw sodium salt is readily soluble in water and inhibits the growth of Staphylococcus aureus at a concentration of 1.2 gamma / ml.
Das erfindungsgemäsee Verfahren wird mit folgendem Beispiel näher erläutert:The method according to the invention is carried out with the following Example explained in more detail:
1,8 g (0,01 Mol) Undecilensfiure wird in 7 ml trockenem Tetrahydrofuran gelöst und diese Lösung unter Rühren mit der Lösung von 2,0 g (0,01 NoI) N,N'-Dicyclohexylcarbodiimid in 5 ml Tetrahydrofuran verse* 1st. Das Reaktionsgemisch wird 10 Minuten weitergerührt. Wahrend dieser Zeit scheidet sich ein weisser Niederschlag au·. Dann wird unter Rühren di· Lösung von 2,6 g (0,01 Mol) des Matriumsalees der 6-APS in 10 ml des Gemisches von Tetrahvdrofuran-Waeeer ItI Eugegeben. Bei Raumtemperatur wird 2 Stunden weitergerührt und dann 60 ml Wasser zugetropft. Der Niederschlag von N, IP-Dicyclohejcjrlharnstoff wird abfiltriert, das FiItrat mit Aether ausgeschüttelt und die Schichten getrennt. Di· wässrige Schicht wird mit Aether überschichtet und durch dl· Zugab· von 10% Schwefelsaure auf den pH-Wert von 2 eingestellt« Mach der Entfernung des Aethers wird die wässrige Schicht noch sweimai mit Aether extrahiert.1.8 g (0.01 mol) of Undecilensfiure is dissolved in 7 ml of dry tetrahydrofuran and this solution with stirring the solution of 2.0 g (0.01 NoI) of N, N'-dicyclohexylcarbodiimide in 5 ml of tetrahydrofuran verse * 1st. The reaction mixture is stirred for a further 10 minutes. During this time they divorce a white precipitate o ·. Then, while stirring, the solution of 2.6 g (0.01 mol) of the matrium alale of 6-APS in 10 ml of the mixture of Tetrahydrofuran-Waeeer ItI E given. at Room temperature is stirred for a further 2 hours and then 60 ml of water are added dropwise. The precipitate of N, IP-dicyclohexylurea is filtered off and the filtrate is extracted with ether and the layers separated. The aqueous layer is covered with ether and made up by adding 10% sulfuric acid the pH is adjusted to 2. After the ether has been removed, the aqueous layer is extracted with ether.
