Patent number: 6960599
Abstract: The invention relates to heterocyclic aminoalkylpyridine derivatives of the formula I: where R1 is 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; R2 is a phenyl group which is optionally monosubstituted, disubstituted, trisubstituted, tetrasubstituted or pentasubstituted by one or more of the groups Hal, -A, —O-A, —NO2 or —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; R3 is H, -A, —CO-A, —C(R4)2R2, —C(R4)2-pyridinediyl-R2; R4 is H or -A; A is C1-C6-alkyl, where 1 to 7 hydrogen atoms are optionally replaced by fluor
