FIELD: chemistry.
SUBSTANCE: present invention relates to a novel method for synthesis of (Z)-3-[2-butoxy-3'-(3-heptyl-1-methylureido)biphenyl-4-yl]-2-methoxyacrylic acid of formula 
(I) and intermediate compounds 
(XII), 
(XIII) and 
(XIV). The disclosed method involves reaction of a sulphonate of formula (XII), where R2 denotes methyl, trifluoromethyl, phenyl or tolyl, with 3-heptyl-1-methyl-1-[3-(4,4,5,5-tetramethyl[1,3,2]dioxaborolan-2-yl)phenyl]urea of formula 
(IIIb) or with a corresponding boronic acid of formula 
(IIIa).
EFFECT: easier synthesis owing to fewer steps.
