Description / Table of Contents:
Synthesis of 2,4,6-Tris(alkylamino)-3-pyridinecarbonitriles by Dimroth Rearrangement2,4,6-Tris(alkylamino)-3-pyridinecarbonitriles 8 are prepared in a three step synthesis starting from N-Alkylcyanoacetamides 5. Key-step in this sequence is the Dimroth rearrangement of the 2(1H)-Pyridinimines 7 which leads in high yield to 8.
Notes:
2,4,6-Tris(alkylamino)-3-pyridincarbonitrile 8 können in einer dreistufigen Synthese aus den N-Alkylcyanessigsäureamiden 5 erhalten werden. Der Schlüsselschritt ist dabei die in hohen Ausbeuten verlaufende Dimroth-Umlagerung der 2(1H)-Pyridinimine 7 zu 8.
