Reaction Steps
In a similar fashion, 3-(2-pyridyl)-5-(5-bromo-2-fluorophenyl)-1,2,4-oxadiazole (100 mg, 0.312 mmole), 4-pyridylboronic acid (76.7 mg,0.6265 mmol) and Pd(PPh3)4 (36.1 mg, 0.03123 mmol) in a solution of 2M sodium carbonate (4 mL) and ethylene glycol dimethyl ether (4 mL) was heated overnight at 105° C. Standard work up, afforded 4.1 mg (4%) of 3-(2-pyridyl)-5-[2-fluoro-5-(4-pyridyl)phenyl]-1,2,4-oxadiazole.
