Reaction Steps

4,6-dichloro-3-[(trans-4-methylcyclohexyl)methyl]-2-[(3R)-3-phenylmorpholin-4-yl]-3H-imidazo[4,5-c]pyridine (3.44 g, 7.49 mmol), 5-chloropyridine-3-boronic acid (1.32 g, 08.39 mmol), cesium carbonate (12.2 g, 37.4 mmol), and 1,1′-Bis(diphenylphosphino)ferrocene-palladium(II)dichloride (1.1 g, 1.49 mmol) were combined in a vial that had been oven-dried and flushed with nitrogen. Dioxane (75 mL) was added, and the vial was sealed and heated to 90° C. for 4 hours. The reaction mixture was cooled to room temperature, filtered over celite, and the filtrate was concentrated under reduced pressure. The residue was purified by silica gel chromatography (0-100% ethyl acetate/hexanes, linear gradient) to afford 6-chloro-4-(5-chloropyridin-3-yl)-3-[(trans-4-methylcyclohexyl)methyl]-2-[(3R)-3-phenylmorpholin-4-yl]-3H-imidazo[4,5-c]pyridine. MS ESI calc'd. for C29H31Cl2N5O [M+H]+ 536. found 536.
