Procedure

2-Chloro-4-methoxypyrimidine (509 mg, 3.52 mmol), 4-chlorophenylboronic acid (826 mg, 5.28 mmol), and sodium carbonate (3732 μl, 7.04 mmol) in toluene (17 ml) were sparged with argon for 2 minutes in a glass vial. Pd(PPh3)4 (203 mg, 0.176 mmol) was added and the reaction mixture was sparged an additional 1 minute. The vial was capped and the reaction heated to 115° C. for 19 hours. The reaction was cooled to ambient temperature and diluted with ethyl acetate. The organic layer was washed with water and brine, dried with sodium sulfate, filtered, concentrated and purified on silica gel. Elution with a 2-20% ethyl acetate/hexanes gradient provided the title compound (161 mg, 0.730 mmol, 20.7% yield) as a white foam.
