Patent ID: 7320977

Claim:
A compound of the formula (I) in which R 1 is 5- to 7-membered, saturated or partially unsaturated heterocyclyl which is linked via a ring nitrogen atom and optionally has a further heteroatom or hetero chain member from the series N, O, S, SO or SO 2 , and which may be substituted once or twice, identically or differently, by substitutents selected from the group of halogen, (C 1 -C 6 )-alkyl, (C 2 -C 6 )-alkenyl, (C 3 -C 8 )-cycloalkyl, hydroxy, oxo, carboxyl, (C 1 -C 6 )-alkoxycarbonyl, (C 1 -C 6 )-alkanoyl, (C 3 -C 8 )-cycloalkylcarbonyl, (C 1 -C 6 )-alkylsulfonyl, aminocarbonyl, and (C 1 -C 6 )-alkylaminocarbonyl, where (C 1 -C 6 )-alkyl and (C 1 -C 6 )-alkanoyl in turn may each be substituted by halogen, hydroxy, (C 1 -C 4 )-alkoxy, (C 1 -C 4 )-alkoxycarbonyl, amino, mono- or di-(C 1 -C 4 )-alkylamino, (C 1 -C 4 )-alkoxycarbonylamino or 5- or 6-membered heterocyclyl having up to two heteroatoms from the series N, O and/or S, or R 1 is 5-membered heteroaryl which is linked via a ring nitrogen atom and has up to two further ring nitrogen atoms, and which may be substituted once to three times, identically or differently, by halogen, (C 1 -C 6 )-alkoxycarbonyl or (C 1 -C 6 )-alkyl which is in turn optionally substituted by hydroxy or halogen, R 2 is (C 6 -C 10 )-aryl which may be substituted once or twice, identically differently, by substituents selected from the group of halogen, nitro, cyano, (C 1 -C 6 )-alkyl, trifluoromethyl, (C 1 -C 6 )-alkanoyl, (C 1 -C 6 )-alkoxy, hydroxy, (C 1 -C 6 )-acyloxy, amino, (C 1 -C 6 )-acylamino, mono- and di-[(C 1 -C 6 )-alkylsulfonyl]amino, where (C 1 -C 6 )-alkyl and (C 1 -C 6 )-alkoxy in turn may each be substituted by hydroxy, amino, (C 1 -C 4 )-alkoxy or (C 1 -C 4 )-acylamino, or R 2 is 5- or 6-membered heteroaryl which has up to two ring nitrogen atoms and which may be substituted by amino, hydroxy, halogen, (C 1 -C 6 )-alkyl or (C 1 -C 6 )-alkoxy, and R 3 is hydrogen, halogen, (C 1 -C 6 )-alkyl, trifluoromethyl, nitro, cyano, carboxyl or (C 1 -C 6 )-alkoxycarbonyl, or a salt, solvate or solvate of a salt thereof.
