From: Formal group insertion into aryl C‒N bonds through an aromaticity destruction-reconstruction process
Plausible reaction pathway. The transformation might proceed via a dearomatization of anilines, an aza-TMM cycloaddition, followed by a subsequent rearomatizing rearrangement and trapping the benzylic carbon cation by nucleophilic attack. PG protecting group. Green scissors mean the bonds there will be cut
