Pd‐catalyzed desulfitative approach to C‐3 arylation of indolizine derivatives has been developed, and the protocol uses readily available arylsulfonylchlorides as the arylation reagent under nitrogen. This transformation was performed in a mixed solvent of 1‐methyl‐2‐pyrrolidone and dimethoxyethane using simple triphenylphosphine as a ligand, which provides a new method for the C‐3 arylation of indolizines
