from quinazoline derivatives and quaternary heterocyclicsalts. An independent synthesis was carried out and transformations of one of the probable intermediates were studied. By-products were isolated. The effects of the nature of the heterocycle and substituents on the course of the ring transformation reaction were found, and the mechanism of the reaction was suggested.

Developed is a technique according to which a nitrogen-containing bicyclic heterocyclic compound can be manufactured directly from nitrogen-containing heterocyclic compounds in a short period of time through a small number of steps without using expensive agents and a starting material that takes time and effort to synthesize. A method for manufacturing a nitrogen-containing bicyclic heterocyclic compound includes a synthesis step of synthesizing a nitrogen-containing bicyclic heterocyclic compound such as bipyrimidine, bipyrazine, or biquinoline by reacting, in a reaction solvent, one nitrogen-containing heterocyclic compound and another nitrogen-containing heterocyclic compound with a solution containing an alkali metal.
Easily accessible and handled ether-imidazolium chlorides were developed as ligand precursors. The coupling reactions of heteroaryl chlorides with aryl/heteroarylboronic acids and esters were catalyzed by the palladium/ether-imidazolium chloride system with high substrate tolerance to give various heterobiaryls in good to excellent yields.
