Synthesis of N-substituted aryl amidines by strong base activation of amines

Tetrahedron Lett. 2015 Jul 1;56(27):4109-4111. doi: 10.1016/j.tetlet.2015.05.029.

Abstract

We describe an efficient method for the direct preparation of N-substituted aryl amidines from nitriles and primary amines. The protocol employs activation of amines by a strong base and provides greater access to a pharmaceutically relevant functional group. This synthetic approach tolerates deactivated nitriles, nitriles with competing substitution sites, and aryl amines.

Keywords: Amidine; amine; base-activation; nitrile; strong base.
