FIELD: chemistry.
SUBSTANCE: invention relates to a method of producing methyl esters of N-aroylpyruvoylanthranilic acids of general formula (I, II) and is characterized by that synthesis is carried out by boiling methyl ether anthranilic acid with methyl esters of aroylpyruvic acids in glacial acetic acid for 15-20 minutes, in the presence of anhydrous sodium acetate.
EFFECT: easy production of desired compounds with high output without using absolute solvents and toxic reagents.
