Reaction Steps

To a solution of 5-bromo-4-methylpyridine-2-carboxylic acid methyl ester (2.207 g, 9.59 mmol), 4-methoxylphenylboronic acid (1.604 g, 10.55 mmol) and 1,1′-bis(di-tert-butylphosphino)ferrocene palladium dichloride (0.313 g, 0.480 mmol) in THF (30 mL) was added potassium carbonate (2.0 M in water, 10.1 mL, 20.15 mmol). The mixture was purged with nitrogen and heated at 50° C. for 1 hour and at 60° C. for 5 hours. The reaction was poured into ethyl acetate and was washed with brine, dried over sodium sulfate, filtered and concentrated. It was purified by column chromatography to yield methyl 5-(4-methoxyphenyl)-4-methylpyridine-2-carboxylate (2.47 g, 9.59 mmol) as a pink solid. MS ESI calc'd. for C15H16NO3 [M+H]+ 258.1. found 258.1.
