Reaction Steps

In a microwave vial, 6-bromo-5-methoxypyridine-2-carbonitrile (9-2, 200 mg, 0.94 mmol, 1.0 equiv), potassium trifluoro(vinyl)borate (314 mg, 2.35 mmol, 2.5 equiv), tricyclohexylphosphine (52.7 mg, 0.19 mmol, 0.2 equiv), palladium(II) acetate (21.1 mg, 0.09 mmol, 0.1 equiv), and tripotassium phosphate (697 mg, 3.29 mmol, 3.5 equiv) were suspended in toluene (10 mL) and water (0.5 mL). The reaction mixture was heated in a microwave reactor for 20 minutes at 130° C. and then filtered, rinsing with EtOAc. The filtrate was concentrated and the residue purified by normal phase column chromatography (10-35% EtOAc in hexanes) to afford the product (9-3). ESI+MS [M+H]+ C9H9N2O: 161.0 found, 161.1 required.
