Title:
METHOD FOR PRODUCING BIPYRIDINE
Document Type and Number:
Japanese Patent JP2006240997
Kind Code:
A
Abstract:

To provide a method for producing di-substituted bipyridines expressed by formula (2) [wherein, R is an alkyl, a carboxy or a group expressed by -CO2M (wherein, M is an alkali metal)] in a good yield.

This method for producing the di-substituted bipyridines expressed by the formula (2) is provided by performing the coupling reaction of halogenopyridines expressed by formula (1) [wherein, X is a halogen atom; R is an alkyl, cyano, carboxy or a group expressed by -CO2M; and M is an alkali metal] in the presence of a palladium catalyst, hydrazines and a base by using a water-soluble aprotic solvent and water as reaction solvent.
