ABSTRACT:
The invention relates to heterocyclic aminoalkylpyridine derivatives of the formula I:whereR1is the radical of a heterocycle having 1 to 3 ring structures, where each ring structure is saturated, unsaturated or aromatic and optionally fused to other ring structures to give a fused ring system and the heterocycle has a total of 1 to 4 N, O and/or S atoms in the ring structures and is optionally monosubstituted, disubstituted or trisubstituted by one or more of the groups -A, —OR4, —N(R4)2, —NO2, —CN, Hal, —COOR4, —CON(R4)2, —COR4, ═O;R2is a phenyl group which is optionally monosubstituted, disubstituted, trisubstituted, tetrasubstituted or pentasubstituted by one or more of the groups Hal, -A, —O-A, —NO2or —CN,or is a thienyl group which is optionally monosubstituted or disubstituted by one or more of the groups Hal, -A, —O-A, -NO2, —CN or thienyl;R3is H, -A, —CO-A, —C(R4)2R2, —C(R4)2-pyridinediyl-R2;R4is H or -A;A is C1-C6-alkyl, where 1 to 7 hydrogen atoms are optionally replaced by fluorine;—X— is —O—, —S—, sulfinyl, sulfonyl, —C(R4)2—;—Y— is —[C(R4)2]n—;—Z— is —C(R4)2—;Hal is F, Cl, Br or I;n is 1, 2, 3 or 4;and their tolerable salts and solvates and their use as medicaments.
