FIELD: organic chemistry, chemical technology.
SUBSTANCE: invention relates to derivatives of piperidine of the general formula (I): 
in free form or as a salt wherein Ar1 means phenyl substituted with one or some halogen atoms; Ar2 means phenyl or naphthyl that can be unsubstituted or substituted with one or some substitutes chosen from the group comprising halogen atom, cyano-, hydroxy-, nitro-group, (C1-C8)-alkyl, (C1-C8)-halogenalkyl, (C1-C8)-alkoxy-group or (C1-C8)-alkoxycarbonyl; R1 means hydrogen atom or (C1-C8)-alkyl optionally substituted with hydroxy-,(C1-C8)-alkoxy-, acyloxy-group, -N(R2)R3, halogen atom, carboxy-group, (C1-C8)-alkoxycarbonyl, -CON(R4)R5 or monovalence cyclic organic group; each among R2 and R3 and independently of one another means hydrogen atom or (C1-C8)-alkyl, or R2 means hydrogen atom and R3 means acyl or -SO2R6, or R and R3 in common with nitrogen atom to which they are bound form 5- or 6-membered heterocyclic group; each among R4 and R5 and independently of one another means hydrogen atom or (C1-C8)-alkyl, or R4 and R in common with nitrogen atom to which they are bound form 5- or 6-membered heterocyclic group; R6 means (C1-C8)-alkyl, (C1-C8)-halogenalkyl or phenyl optionally substituted with (C1-C8)-alkyl; n means 1, 2, 3 or 4 under condition that when Ar1 means para-chlorophenyl and R1 means hydrogen atom then Ar2 doesn't mean phenyl or para-nitrophenyl. Compounds of the formula (I) possess the inhibitory CCR-3 activity and can be used in medicine.
EFFECT: improved preparing method, valuable medicinal properties of compounds.
