FIELD: chemistry.
SUBSTANCE: invention relates to organic chemistry, specifically to a method of producing imides of maleopimaric acid. Method involves condensation of methyl ether of maleopimaric acid with amines in an organic solvent at high temperature with subsequent cooling of reaction mass to room temperature and addition of water for extraction of end product. Method is characterised by that molar ratio of methyl ether of maleopimaric acid: amine is equal to 1:2, organic solvent used is dimethyl sulphoxide, and process takes place at temperature 120-160 °C under conditions of ultrasonic action during 30-40 minutes.
EFFECT: method increases output of end products and reduces duration of synthesis.
