Reaction Steps

6,7-Dichloro-2-[4-(2-morpholin-4-ylethoxy)phenyl]-3H-imidazo[4,5-b]pyridine (Example 206) (0.050 g, 0.13 mmol), 4-methylphenylboronic acid (0.027 g, 0.19 mmol), K2CO3 (0.097 g, 0.70 mmol) and Pd(PPh3)4 (0.029 g, 0.025 mmol) were mixed in a vial. Dioxane (3 ml) was added and the reaction mixture was heated to 100° C. under argon for 4 h. EtOAc (50 ml) was added and the solution was washed with water. Drying (Na2SO4) and evaporation gave crude material which was purified by column chromatography (dichloromethane/methanol, 95:5), giving the title product (0.019 g, 33%).
