Abstract
A target bipyridine compound is synthesized with high purity and a high yield in a simple and safe manner in a short period of time. A method for synthesizing a di-tert-butyl-2,2'-bipyridine compound is provided, and the method includes a step of reacting, in a reaction solvent, a tert-butylpyridine compound with a dispersion product obtained by dispersing an alkali metal in a dispersion solvent. A method for synthesizing a bipyridine compound having no substituents is also provided, and the method includes a step of reacting, in a reaction solvent, pyridine with a dispersion product obtained by dispersing an alkali metal in a dispersion solvent.
