Reaction Steps

3-Chlorophenylboronic acid (CAN 63503-60-6, 0.61 g, 3.9 mmol), 1,1′-bis(diphenyl-phosphino)ferrocene-palladium(II)dichloride methylene chloride complex (CAN 95464-05-4, 53 mg, 0.065 mmol) and potassium carbonate (CAN 584-08-7, 0.54 g, 3.9 mmol) was added to a solution of 6-bromo-5-methyl-pyridine-2-carboxylic acid (0.7 g, 3.2 mmol) in water (30 mL). The mixture was stirred at 100° C. overnight. The reaction mixture was adjusted to pH=3 and the mixture was extracted with ethyl acetate (3×20 mL). The organic layers were combined, dried over anhydrous sodium sulfate and concentrated in vacuo to give product (0.55 g, 56.9%); MS (EI): m/e 248.1 [M+H]+.
