N-heterocyclic carbene, were synthesized in high yields using a two-step procedure starting from commercially available amino alcohols. In situ prepared corresponding carbenes were tested in palladium-catalyzed C(sp3)−H arylation of 4-benzylpyridine with aryl bromides, affording triarylmethane derivatives in high yields.
