In the absence of any additional ligands, the efficientN-arylation of nitrogen-containing heterocycles with aryl iodides catalyzed by relative low catalyst amount of Cu(OAc)2·H2O was developed. This simple catalytic system is involved in the C–N cross-coupling reaction and works for a variety of pyrazole, pyrrole, imidazole, triazole, indole, benzoimidazole, benzotriazole, carbazole, and anilines
Described herein are compounds, pharmaceutical compositions and methods for the inhibition of RAF kinae mediated signaling. Said compounds, pharmaceutical compositions and methods have utility in the treatment of human disease and disorders.
