Reaction Steps

Add 1-{2-[2-(4-bromo-phenyl)-5-methyl-oxazol-4-yl]-ethyl }-2-methylpiperidine (0.724 g, 1.99 mmol), Pd(Ph3)4 (0.101 g, 0.088 mmol), 4-pyridylboronic acid (0.367 g, 2.99 mmol), 2N Na2CO3 (5 mL), and 1,4-dioxane (1.5 mL) to a microwave vessel. Subject the reaction mixture to microwave irradiation at 30 W, 90° C. for 30-45 minutes. Concentrate and purify on silica gel eluting with 10% 2N NH3 in methanol/dichloromethane to give 4-(4-{5-methyl-4-[2-(2-methyl-piperidin-1 -yl)-ethyl]-oxazol-2-yl}-phenyl)-pyridine (0.059 g, 10%).
