Procedure

2-Chloro-pyrimidin-4-ylamine (1 g, 7.7 mmol), 4-methoxybenzeneboronic acid (1.41 g, 9.26 mmol) and dimethylacetamide (12 mL) were added to a microwave tube containing a stirrer bar, potassium phosphate (3.28 g, 15.44 mmol) was dissolved in water (4 mL) and added to the vial. The tetrakis(triphenylphosphine)palladium (0.44 g, 0.386 mmol) was added and the reaction was heated to 150° C. for 10 min. The reaction was filtered through silica and washed through with methanol and concentrated. Yield: 1.10 g, 71%; LCMS method: 1, RT: 3.43 min, MI: 241 [M+1].
