Patent ID: 8633316

Claim:
A method for producing a nitrogen-containing condensed heterocyclic compound comprising the step of: reacting a compound represented by Formula (4a) with a compound represented by Formula (2) in the presence of Cu 2 O or CuO, and a ligand selected from the group consisting of picolinic acid, a 5-butylpicolinic acid and dipivaloylmethane to produce a nitrogen-containing condensed heterocyclic compound represented by Formula (5a): wherein “A” represents an aromatic hydrocarbon ring or an aromatic heterocycle; Z 1 represents a non-metallic atomic group necessary to from an aromatic heterocycle; Z 2 represents a non-metallic atomic group necessary to form an aromatic hydrocarbon ring or an aromatic heterocycle; and “n” represents an integer of 1 to 4.
