Description

  • Verfahren zur Darstellung substituierter Guanidine Während Cyanamid und Monoalkylcyanamide sehr bequem mit Aminsalzen reagieren, insbesondere wenn man in sehr konzentrierter Lösung arbeitet, wie dies in der Patentschrift 512 88o angeführt wurde, reagieren disubstituierte Cyanamide mit Aminen oder Aminsalzen nicht (vgl. L e c h e r und D e m m 1 e r, Zeitschrift für physiologische Chemie, Bd. 167 [i927], S. 17o).
  • Es wurde nun gefunden, daß Dialkylcyanamide dann sehr leicht mit Aminsalzen reagieren, wenn man sie in Gegenwart von freien Aminen zusammenbringt. Bei manchen Derivaten ist es dabei nicht einmal nötig, die Temperatur zu erhöhen. Der Grund dieser eigenartigen Reaktion ist noch nicht sicher aufgeklärt, möglicherweise entsteht ein Zwischenprodukt folgender Konstitution das mit dem Amin weiterreagiert. Beispiel i 5 Teile Diäthylcyanamid mit 6,5 Teilen Anilinchlorhydrat und 3 Teilen Anilin i o Stunden auf i oo° erhitzt, geben das N, N-Diäthyl-N'-phenylguanidin, das als ölige Base durch Wasserdampfdestillation des alkalisierten Ansatzes gewonnen wird oder, als Pikrat vom Schmelzpunkt i 18° abgeschieden werden kann. Anilin reagiert übrigens auch ohne Chlorhydratzusatz mit dem Dialkylcyanamid; die Ausbeuten an Guanidin sind jedoch in ersterem Falle günstiger.
  • Beispiele 2,7 Teile Diäthylcyanamid, 5 Teile Isoamylainin und 7 Teile Isoamylaminchlorhydrat geben beim längeren Stehen oder bei etwa. istündigem Erhitzen auf ioo° das N,N-Diäfhyl-N'-isoamylguanidin, dessen Halogenwasserstoffsalze leicht wasserlöslich sind Lind dessen Pikrat bei i2o° schmilzt.
  • Beispiel 3 3 Teile Dimethylcyariarnid auf die gleiche Weise wie in Beispiele behandelt (q. Teile Amin, 5 Teile C'hlorhydrat), geben das N,N-Dimet'hyl - N' - isoamylguanidin. Das Pikrat schmilzt bei 1o4°.
  • Beispiel q.
  • 2 Teile Dimethylcyanamid, 1,9 Teile @thvlamin, 3,5 Teile Äthylaminchlorhydrat geben nach einigem Stehen das N, N-Dimethyl-N'-äthyIguanidin; Pikrat: Schmelzpunkt 152°. Beispiel 5 2o g Diphenylcyanamid werden in Gegenwart von wenig Alkohol b Stunden mit 1 o g Anilin und 13 g Anilinchlorhydrat erhitzt. Aus dem Reaktionsprodukt läßt sich das Triphenviguanidin vom Schmelzpunkt 133° in sehr guter Ausbeute isolieren.
