N-Arylation of azaindoles in LiCl-mediated catalytic CuI reactions

N-Arylation of 5- and 7-azaindoles was achieved in LiCl-mediated catalytic CuI reactions at 120 °C with moderate to high yields. N-Arylation can be performed with various arylhalides, such as phenyl, pyridine, quinoline, thiophen, and thiazole moieties.
