Title:
METHOD FOR PRODUCING IMIDAZOPYRIDINE DERIVATIVE
Document Type and Number:
WIPO Patent Application WO/2022/163764
Kind Code:
A1
Abstract:
Provided is a method for producing an imidazopyridine derivative represented by formula (I), wherein, in formula (I), X is H, a substituted or unsubstituted propenyl group, a substituted or unsubstituted propinyl group, or a substituted or unsubstituted aryl group and Y is H or OH, and the production method includes a step for conducting a coupling reaction of a compound having a 5-X-2-thienyl group with 2-amino-3-nitro-4-chloropyridine under Suzuki-Miyaura coupling reaction conditions to obtain 2-amino-3-nitro-4-(5-X-2-thienyl)pyridine.
