    摘要: The present invention relates to a process for producing a 4-quinolone derivative, comprising allowing an o-aminoacetophenone derivative to react with a formic acid in an aprotic solvent in the presence of a suitable base, and adding a protic solvent to the reaction mixture. This is a simple process for producing 4-quinolone derivatives, applicable to large-scale commercial production.
