Diarylamines find use as metal ligands and as structural components of drug molecules, and are commonly made by metal‐catalyzed C−N coupling. However, the limited tolerance to steric hindrance of these couplings restricts the synthetic availability of more substituted diarylamines. Here we report a remarkable variant of the Smilesrearrangement that employs readily accessible N‐aryl anthranilamides
