Title:
METHOD FOR PRODUCING COMPOUND REPRESENTED BY FORMULA (I)
Document Type and Number:
WIPO Patent Application WO/2023/136334
Kind Code:
A1
Abstract:
This method for producing a compound represented by formula (I) involves forming at least one bond between a carbon atom and a nitrogen atom in an aromatic ring of the compound represented by formula (I) through a reaction using a palladium catalyst or a nickel catalyst. In formula (I), each of Ar1 to Ar4 independently represents an aryl group or a heteroaryl group, each of Ra to Rc independently represents a monovalent substituent, each of na and nb independently represents an integer of 0-3, nc represents an integer of 0-4, L represents C=O or SO2, A represents O, S, NRd, CRdRe, or SiRfRg, each of Rd and Re independently represents a hydrogen atom or an alkyl group having 1-20 carbon atoms, and each of Rf and Rg independently represents an alkyl group having 1-20 carbon atoms.
