Abstract:
PROBLEM TO BE SOLVED: To provide a nitrogen-containing fused heterocyclic compound obtainable at a low catalyst amount and in a high yield even in the case of using a bromide as a raw material. SOLUTION: This method for producing the nitrogen-containing fused heterocyclic compound is provided by reacting a nitrogen-containing fused heterocyclic compound having a secondary nitrogen atom with a bromine compound having an oxygen-containing heterocyclic residue or a nitrogen-containing heterocyclic residue in the presence of copper or copper ion with a ligand, and performing dehydrobromination for bonding the corresponding nitrogen-containing fused heterocyclic compound with the compound having the oxygen-containing heterocyclic residue or the nitrogen-containing heterocyclic residue.
