Abstract

A palladium-catalyzed ortho-arylation of aromatic amides ­directed by [4-chloro-2-(1H-pyrazol-1-yl)phenyl]amine as a bidentate auxiliary has been established. The reaction is characterized by normal working conditions, a broad substrate scope, and a wide functional-group tolerance. In particular, the protocol is compatible with highly sterically demanding ortho-substituted anilides and aryl iodide partners, with good yields.

• 9 Products 3 and 4; General Procedure A mixture of substrate 1 (0.3 mmol), (het)aryl iodide 2 (0.9 mmol), Pd(OAc)₂ (6.7 mg, 10 mol%), and Ag₃PO₄ (125.6 mg, 1.0 equiv) in p-xylene (2.5 mL) was stirred and then heated at 120 °C for 12 h. Upon completion of the reaction, the mixture was cooled to r.t. and filtered through a pad of Celite. The filtrate was washed with EtOAc (3 × 15 mL) and the organic layers were combined, dried (MgSO₄), and concentrated in vacuo to provide a crude product that was purified by column chromatography [silica gel, PE–EtOAc (40:1)] to give the desired product 3 or 4.
