A process for producing an N-(hetero)aryl-substituted nitrogen-containing heteroaryl compound, the process comprising: reacting a heteroaryl compound having an NH group as a ring-constituting component with a (hetero)aryl compound having a leaving group in the presence of a heterogeneous-system platinum group metal catalyst, a ligand and a base.

Process for producing N-(hetero)aryl-substituted nitrogen-containing heteroaryl compound

A process for producing a 2-pyridylpyridine derivative usable as an intermediate for medicines or agricultural chemicals is provided, which does not require expensive special catalysts and special equipment, which does not cause environmental problems, and which can be conducted on an industiral scale. The process comprises reacting an acetyl-substituted pyridine derivative with a 3-amino acrolein, then reacting the reaction product with ammonia or an ammonium salt.
