FIELD: chemistry.
SUBSTANCE: invention relates to methods for synthesis of 1,2,4-oxadiazoles of formula: 
where R1 is a substituted or unsubstituted alkyl or -(CH2CH2O)nR6; R6 is hydrogen, substituted or unsubstituted alkyl, X in each case is independently F, C, Br or I, n equals an integer from 1 to 7, and m equals an integer from 1 to 5, which are used to produce 3-[5-(2-fluorophenyl-[1,2,4]oxadiazol-3-yl]benzoic acid.
EFFECT: method for synthesis of 1,2,4-oxadiazoles.
