METHOD FOR PREPARING QUINOLONE COMPOUND AND INTERMEDIATE THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/201780
Kind Code:
A1
Abstract:
Provided is a method for preparing a quinolone compound and an intermediate thereof, particularly, a method for preparing quinolone and a pharmaceutical quinolinone intermediate. Specifically, provided are a method for preparing a compound represented by formula I and a method for synthesizing a quinolone compound using the compound represented by formula I as an intermediate. The method for preparing the compound represented by formula I comprises the following step: reacting a compound represented by formula A with R5NH2 and R6Cl in the presence of a base to generate the compound represented by formula I.
