Reaction Steps

A sealed tube was charged with 2-bromo-4-(5-chloropyridin-3-yl)-3-[(trans-4-methylcyclohexyl)methyl]-3H-imidazo[4,5-c]pyridine-6-carbonitrile (Preparative Example 3.1, 150 mg, 0.337 mmol), 4,4,5,5-tetramethyl-2-(1-phenylethenyl)-1,3,2-dioxaborolane (93 mg, 0.405 mmol), PdCl2(dppf)-dichloromethane adduct (27.5 mg, 0.034 mmol), and potassium phosphate (215 mg, 1.012 mmol). The tube was evacuated and backfilled with argon (3×). Fully degassed dioxane (1.53 mL) and water (0.153 mL) were added. The vial was sealed and heated at 50° C. overnight. The mixture was then cooled to room temperature and directly purified via silica gel chromatography (0-100% ethyl acetate/hexanes) to afford 4-(5-chloropyridin-3-yl)-3-[(trans-4-methylcyclohexyl)methyl]-2-(1-phenylethenyl)-3H-imidazo[4,5-c]pyridine-6-carbonitrile as a yellow solid. MS ESI calcd. for C28H26ClN5 [M+H]+ 468. found 468.
