Title:
PRODUCTION METHOD FOR COMPOUND
Document Type and Number:
WIPO Patent Application WO/2023/120358
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a production method with which a condensed ring compound can be obtained at good yield. The present invention relates to a production method for a compound (II) represented by formula (2), the method including a step for reacting a compound (I) represented by formula (1) and a Brønsted acid having a pKa in water of no more than -9. (In the formulas, ring ArA and ring ArB independently represent carbon rings or heterocyclic rings, where the rings may have substituents. Rr represents the group represented by formula (r1) or the group represented by formula (r2). R1 and R2 independently represent alkyl groups or the like, where the groups may have substituents. Ra represents a hydrogen atom, an alkyl group, or the like, where the group may have a substituent. Ring ArC and ring ArD independently represent carbon rings or heterocyclic rings, where the rings may have substituents.)
