FIELD: chemistry.
SUBSTANCE: invention relates to new derivatives of imidazo[1,2-c]pyrimidinyl acetic acid of formula (I) or to its salts: , where R1 is
,
, in which n is an integer ranging from 0 to 6; Y is aryl, where the said aryl is optionally substituted at a substitutable position with one or more substitutes selected from a group which consists of halogen or C1-6alkyl, optionally substituted with mono-, di- or trihalogen; R2 is hydrogen; R3 is hydrogen or halogen; and R4 is hydrogen. The invention also relates to derivatives of imidazo[1,2-c]pyrimidinyl acetic acid of formula (I-i) or to its salts, to a drug, to use of compounds in paragraph 1, as well as to a drug in form of a standard single dosage.
EFFECT: obtaining new biologically active compounds, which are active towards CRTH2.
