Participants

Reaction Steps

Mixture of 5-chloro-2-methoxyphenylboronic acid (5.0 g, 26.8 mmol), 5-chloro-3-iodopyridin-2-amine (6.83 g, 26.8 mmol), sodium carbonate (8.53 g, 80.5 mmol in 50 mL of water), Pd(PPh3)4 (621 mg, 2 mol. %) and 100 mL of toluene was refluxed overnight under N2. reaction mixture was cooled down to room temperature, organic layer was separated and concentrated in vacuum. The residue was subjected to column chromatography on silica gel with hexane/ethyl acetate gradient mixture as eluent, providing 3.3 g (46% yield) of 5-chloro-3-(5-chloro-2-methoxyphenyl)pyridin-2-amine.
