Elaborating amines via C-H functionalization has been an important area of research over the past decade but has generally relied on an added directing group or sterically hindered amine approach. Since free-amine-directed C(sp3)-H activation is still primarily limited to cyclization reactions and to improve the sustainability and reaction scope of amine-based C-H activation, we present a strategy

diversification of pharmaceuticals. However, to date, the direct functionalization of the meta position of amine substrates lacking additional directinggroups remains underexplored. In this Letter, we present a successful meta-C–H arylation of free primary amine derivatives using aryl iodides, resulting in synthetically valuable yields. This meta-selective C–H functionalization is achieved through a sequence
