The essence of the invention consists in arylation of 3,5-diiodo-4-(4'-methoxyphenoxy)benzylcyanide with iodonium salts, namely 4,4'-dimethoxydiphenyliodonium bromide, sulfate or trifluoroacetate in the presence of the base and copper powder at room temperature. The molar ratio of the iodonium salts, 3,5-diiodo-4-hydroxybenxylcyanide, base and copper powder is 2:1:1:(0.2-0.25). The synthesis is performed in the medium of organic solvent. According to the method proposed two iodine atoms are introduced into the molecules of one of the reagents, namely 3,5-diiodo-4-hydroxybenxylcyanide, prior to the synthesis. These atoms appear in the prototype molecule upon substitution of diazo group by iodine (Zandmeyer reaction). The method proposed is simple, ecologically safe and allows one to spare the production costs due to employing non-expensive ingredients.
