Description

  

  Verfahren zur Herstellung eines     cyclischen    Amins.    Es wurde gefunden, dass man zu einem       cyclischen    Amin gelangen kann, wenn man  auf     Cycloheptadecanon-thioisoxim        (Lactam     der     17-Amino-heptadecanthionsäure)    ein Re  duktionsmittel einwirken lässt.  



  Das auf diese Weise erhaltene     Hepta-          decamethylenimin    der Formel

  Das neue Amin zeichnet sich durch seine  physiologische Wirkung aus und soll thera  peutische Verwertung     finden.            Beispiel   <I>;</I>  1 Gewichtsteil     Cycloheptadecanonoxim     wird mit 2-3 Gewichtsteilen starker Schwe  felsäure, hergestellt durch Mischen von 4  Raumteilen konzentrierter Schwefelsäure und  1 Raumteil Wasser, über freier Flamme er  hitzt. Sobald die anfänglich rotorange Farbe  der Lösung in braun übergegangen ist, wird    auf Eis gegossen, das Reaktionsprodukt mit  Äther ausgezogen und aus Aceton umkristal  lisiert. Das.     Cycloheptadecanon-isoxim        (Lactam     der     17-Amino-heptadecansäure    schmilzt bei  124-1250.  



  Ein Gewichtsteil des     Isoxims    wird in  10 Raumteilen     gylol    gelöst und unter Rühren  mit der Turbine mit 0,9 Gewichtsteilen     Phos-          phorpentasulfid    versetzt. Das Gemisch erhitzt  man allmählich auf 100   und lässt es 2 Stun  den bei dieser Temperatur. Man fügt dann  Natronlauge zu und erhitzt weiter, bis alles  in Lösung geht. Nach Abtrennung der     Xylol-          schicht    und Verdampfung des Lösungsmittels  wird der Rückstand aus Benzin umkristalli  siert.

  1 Gewichtsteil     Thioisoxim    wird in der       40-fachen    Menge absolutem Alkohol gelöst,  mit der     17-fachen    Menge Eisessig versetzt  und dann dazu unter starkem Sieden und  kräftigem Rühren die     6-fache    Menge Natrium  eingetragen. Der Alkohol wird dann im Va-           kuum        abdestilliert    und der Rückstand in  Wasser aufgelöst: Die wässerige Lösung  scheidet beim Übersättigen mit Lauge das       Heptadecamethylenimin    ab.

  Die Reduktion des     Thioisogims    kann  beispielsweise auch auf elektrolytischem Wege  vorgenommen werden.



  Process for the preparation of a cyclic amine. It has been found that a cyclic amine can be obtained if a reducing agent is allowed to act on cycloheptadecanone thioisoxime (lactam of 17-amino-heptadecanthionic acid).



  The heptadecamethyleneimine of the formula obtained in this way
EMI0001.0008
    melts at <B> 64-66. </B>



  The new amine is characterized by its physiological effect and should be used therapeutically. Example <I>; </I> 1 part by weight of cycloheptadecanone oxime is heated with 2-3 parts by weight of strong sulfuric acid, prepared by mixing 4 parts by volume of concentrated sulfuric acid and 1 part by volume of water, over a free flame. As soon as the initially red-orange color of the solution has turned brown, it is poured onto ice, the reaction product extracted with ether and recrystallized from acetone. The. Cycloheptadecanone isoxime (lactam of 17-amino-heptadecanoic acid melts at 124-1250.



  One part by weight of the isoxime is dissolved in 10 parts by volume of gylene and 0.9 parts by weight of phosphorus pentasulphide are added while stirring with the turbine. The mixture is gradually heated to 100 and left for 2 hours at this temperature. Sodium hydroxide solution is then added and heating continues until everything goes into solution. After the xylene layer has been separated off and the solvent has evaporated, the residue is recrystallized from gasoline. The cycloheptadecanone-thio-isoxime obtained melts at 110-1110.



  1 part by weight of thioisoxime is dissolved in 40 times the amount of absolute alcohol, 17 times the amount of glacial acetic acid is added, and 6 times the amount of sodium is then added with vigorous boiling and vigorous stirring. The alcohol is then distilled off in vacuo and the residue is dissolved in water: the aqueous solution separates the heptadecamethyleneimine when it is oversaturated with lye. It is distilled in a vacuum and solidifies when it cools.



  The thioisogime can also be reduced, for example, by electrolytic means.
