FIELD: organic chemistry, biochemistry, chemical technology. SUBSTANCE: invention relates to a novel method of synthesis of compounds of the formula (I): 
where A means C1-C6-alkyl, aryl that is mono- or di-substituted with F, Cl, Br, OCH3, C1-C3-alkyl or benzyl. These compounds are inhibitors of 5-lipoxygenase and useful in treatment of inflammatory diseases, allergy and cardiovascular diseases. Invention relates to also novel compounds of the formula (I) where A is -C1-C6 and to intermediate compounds of the formula (VIII): 
where X is Br or Cl that is necessary for synthesis of compounds of the formula (I). EFFECT: development of novel, simplified and low-priced method of synthesis of 5- lipoxygenase inhibitors. 26 cl, 6 ex
