FIELD: chemistry.
SUBSTANCE: invention relates to novel derivatives of 2- pyrrolidine-2-yl-[1, 3, 4]oxadiazole with common formula I 
where R1 is aryl or heteroaryl, aryl here being phenyl unsubstituted or substituted with F, Cl, O-alkyl or phenyl, whereas heteroaryl is pyridinyl or thyenyl, R2 designates H, SO2R3 or COR4 where R3 and R4 independently designate C1-C10alkyl, C3-C10cycloalkyl, (C1-C6alkyl)-C3-C10cycloalkyl, aryl, (C1- C6alkyl)aryl, heterocyclyl, carboxylate residues with 3-10 C-atoms, dimethylamide or NR5R6, C1-C10alkyl at that being methyl, propyl, butyl, butenyl, isobutyl, amyl, pent-3-yl, hept-3-yl, hept-4-yl, 2,2-dimethylpropyl, CH2OCH3, CH2O(CH2)2OCH3 or CH(benzyl)MSO2C6H4CH3, C3-C10cycloalkyl is cyclopropyl, cyclobutyl, cycloamyl, adamantane-1-yl, 2-phenylcyclopropyl or 4,7,7-trimethyl-2-oxabicyclo[2.2.1]heptane-3-on-1-yl, (C1-C6alkyl)-C3-C10cycloalkyl is CH2-cycloamyl, (CH2)2-cycloamyl or 7,7-dimethyl-1-methylbicyclo[2.2.1]heptane-2-on, aryl is phenyl, benzyl or naphthyl unsubstituted, monosubstituted or polysubstituted with identical or different substitutes, namely: phenyl, NO2, C1-C6alkyl, O-alkyl, CO2-alkyl, C(=O)C1-C6alkyl, CH2OC(=O)C6H5, F, Cl, Br, N(CH3)2, OCF3, CF3 or (C=O)CH3, (C1-C6alkyl)aryl is 3,4-dimethoxyphenyl-CH2, 4-chlorophenoxy-CH2, phenyl-CH=CH, benzyl-OCH2, phenyl-(CH2)2, 2-bromphenyl-CH2, 1-phenylpropyl, 2-chlorophenyl-CH=CH, 3-trifluorinemethylhenyl-CH=CH, phenoxy-CH2, phenoxy-(CH2)3 or phenoxy-CH(CH3), heterocyclyl is pyridinyl, isoxazole, thienyl, furanyl, triazole, benzoxadiazole, thiadiazole, pyrazole or isoquinoline unsubstituted, monosubstituted or polysubstituted with identical or different substitutes, namely: Cl, C1-C6alkyl, phenyl, in their turn unsubstituted or mono- or polysubstituted with identical or different substitutes, namely: Cl or C1-C6alkyl, CF3, carboxylate residues with 3-10 C-atoms are CH3OC(=O)CH2, CH3OC(=O)(CH2)3, CH3CH2OC(=O)CH2, CH3CH2OC(=O)(CH2)2, CH3C(=O)OCH2, CH3C(=O)OC(CH3)2 or CH3C(=O)OCH(C6H5), and R5 and R6 independently designate H or aryl, aryl at that being benzyl or phenyl respectively mono- or polysubstituted with identical or different substitutes, namely: F, C1, O-alkyl, CN, CF3. Invention also relates to method of obtaining, to medicament and to use of compounds with common formula I.
EFFECT: obtaining of new biologically active compounds and medicinal agents based on the above formulas.
