A mixture of 6-chloro-4-(5-chloropyridin-3-yl)-3-[(trans-4-methylcyclohexyl)methyl]-2-[(3R)-3-phenylmorpholin-4-yl]-3H-imidazo[4,5-c]pyridine (Example 2.1, Step 3; 130 mg, 0.242 mmol), 2-methoxy-6-(tri-n-butylstannyl)pyridine (122 mg, 0.308 mmol), and Pd(PPh3)4 (28.0 mg, 0.0242 mmol) in DMF (2.9 mL) was degassed and heated at 100° C. for 16 hours under a nitrogen atmosphere. The reaction mixture was cooled to room temperature and diluted with water (10 mL). The reaction mixture was extracted with ethyl acetate (3×10 mL). The combined organic layers were washed with saturated aqueous KF solution (10 mL), water (2×10 mL) and brine (10 mL). The organic layer was dried over anhydrous Na2SO4, filtered, and concentrated. Purification of the residue on a silica gel column (0 to 50% EtOAc/hexanes) afforded 4-(5-chloropyridin-3-yl)-6-(6-methoxypyridin-2-yl)-3-[(trans-4-methylcyclohexyl)methyl]-2-[(3R)-3-phenylmorpholin-4-yl]-3H-imidazo[4,5-c]pyridine. MS ES calc'd. for C35H37ClN6O2 [M+H]+ 609. found 609.
