FIELD: chemistry.
SUBSTANCE: invention relates to the method for producing betulinol diphtalate of the formula 
by means of the betulinol acylation, wherein the acylating agent is represented by phthalic acid, and the acylation is carried out by fusing betulinol with phthalic acid at the temperature of 180-200°C for 2-3 minutes at a molar ratio of betulinol and phthalic acid equal to 1:3, with the subsequent recrystallization of the desired product from ethanol.
EFFECT: simplification of the process of obtaining betulinol diphtalate, increasing its economic efficiency due to reducing the process time and excluding the use of expensive and toxic reagents.
