To a solution of 5-(bromomethyl)-3-(3-chlorophenyl)-2-methoxypyridine (Intermediate 2, 100 mg, 0.321 mmol), (2-chloropyrimidin-5-yl)boronic acid (76 mg, 0.481 mmol) in ACN (3.2 mL) was added NaHCO3 (417 mg, 1.282 mmol) and PdCl2(dppf)-DCM (23 mg, 0.032 mmol). The reaction was heated under microwave conditions, at 120° C. for 12 minutes. Water was removed from the reaction with a pipette, and the crude reaction mix was filtered thru CELITE®, and washed with EtOAc. The combined organics were dried (Na2SO4), filtered and concentrated onto silica. Purification (FCC, SiO2, 30-70% EtOAc/hexanes) afforded the title compound (61 mg, 55%). 1H NMR (400 MHz, DMSO-d6) δ 8.34 (s, 2H), 8.11 (d, J=2.0 Hz, 1H), 7.70 (d, J=2.0 Hz, 1H), 7.58 (t, J=1.8 Hz, 1H), 7.53-7.36 (m, 3H), 3.83 (s 2H), 3.73 (s, 3H). [M+H]=346.11.
