A Pd(II)-catalyzed intramolecular C-H amination of 2-pyridinesulfonyl-protected phenethylamine derivatives using PhI(OAc)2 as a bystanding oxidant provides access to various substituted indoline derivatives in good yields. The use of the 2-pyridinesulfonyl protecting group enables a facile deprotection following C-H functionalization.
