To a mixture of methyl 6-chloropyridine-2-carboxylate, 3,4-dimethoxyphenylboric acid, dimethoxyethane and water were added palladium acetate, triphenylphosphine and sodium carbonate, and they were reacted at 100° C. for 1 hour to obtain methyl 6-(3,4-dimethoxyphenyl)pyridine-2-carboxylate. Thus obtained compound was reacted at 60° C. for 30 minutes in a mixed solution of THF-methanol with adding a 1M aqueous sodium hydroxide solution, whereby 6-(3,4-dimethoxyphenyl)pyridine-2-carboxylic acid was obtained.
