METHOD OF PRODUCING N-ARYLAMIDES OF AROLYLPIROINBURGATE ACIDS Russian patent published in 2017 - IPC C07C233/56 C07C311/16 C07D277/46 

Abstract RU 2624226 C2

FIELD: chemistry.

SUBSTANCE: invention relates to a process of preparation of aroyl pyruvic acid N-arylamides of the general formula I-III

,

wherein

.

The process of N-arylamides of aroyl pyruvic acids is carried out by boiling the arylamines with methyl esters of aroylpyruvic acids in glacial acetic acid for 15-20 minutes in the presence of anhydrous sodium acetate.

EFFECT: preparation of N-arylamides of aroyl pyruvic acids in high yield, in the absence of dry solvents and toxic reagents.
