Producing method of nitrogen containing condensed heterocyclic compound
View Patent ↗Provided is a method for producing a nitrogen-containing condensed heterocyclic compound containing the step of: reacting a compound represented by Formula (1a) or Formula (1b) with a compound represented by Formula (2) under existence of cupper or a cupper ion, and a ligand to produce a nitrogen-containing condensed heterocyclic compound represented by Formula (3a) or Formula (3b):
1. 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.
2. The method for producing a nitrogen-containing condensed heterocyclic compound of claim 1 ,
wherein the reaction is carried out in the presence of a base.
3. The method for producing a nitrogen-containing condensed heterocyclic compound of claim 1 ,
wherein “A” represents one selected from the group consisting of a benzene ring, a dibenzofuran ring, a dibenzothiophen ring, and a carbazole ring.
4. The method for producing a nitrogen-containing condensed heterocyclic compound of claim 1 ,
wherein “A” represents one selected from the group consisting of a dibenzofuran ring, a dibenzothiophene ring, and a carbazole ring.
5. The method for producing a nitrogen-containing condensed heterocyclic compound of claim 1 ,
wherein the ligand is at least one of 5-butylpicolinic acid and dipivaloylmethane.
