General procedure: Under N2 atmosphere, to a solution of palladium acetate (120 mg, 0.53 mmol, 5 mol %) and XANTPHOS (309 mg, 0.53 mmol, 5 mol %) in anisole (30 mL) was added 3-bromo-5-methyl-pyridin-2-ylamine (5) (2.0 g, 10.7 mmol, 1.0 equiv), aryl iodides (6) (10.7 mmol) and cesium carbonate (4.9 g, 15.0 mmol, 1.4 equiv), and the mixture was stirred at 130 C for 1-13 h. After cooling to room temperature, water (40 mL) was added to the mixture. The mixture was concentrated in vacuo and ethyl acetate (100 mL) was added to the residue. The organic layer was washed with water (20 mL) and concentrated in vacuo to give the crude product, which was purified by flash chromatography to give 7.
