Patent ID: 7405201

Claim:
An antibacterial compound of the general formula (I) in which R 1 denotes halogen, R 2 is hydrogen or halogen, R 5 denotes hydrogen, C 1 -C 4 -alkyl, fluorine or chlorine, R 6 denotes hydrogen, halogen or alkyl, R 7 denotes alkyl or (cycloalkyl)alkyl, R 8a denotes alkyl, alkylene, cycloalkyl or (cycloalkyl)alkyl, where R 8a optionally can be substituted by 1, 2 or 3 substituents, which independently of one another are selected from the group consisting of hydroxyl, alkoxy, a radical —OR 8a-1 , carboxyl, alkoxycarbonyl, amino, alkylamino, dialkylamino, aminocarbonyl, alkylaminocarbonyl, dialkylaminocarbonyl, aminosulfonyl, alkylaminosulfonyl, dialkylaminosulfonyl, arylaminosulfonyl, heterocyclylaminosulfonyl, heteroarylaminosulfonyl, aminocarbonylamino, hydroxycarbonylamino, alkoxycarbonylamino, aminocarbonyloxy, in which R 8a-1 is a carbonyl-bonded amino acid radical, or R 7 and R 8a , together with the carbon atom to which R 8a is bonded and the nitrogen atom to which R 7 is bonded, form a heterocyclyl ring, which optionally can be substituted by 1, 2 or 3 substituents, which independently of one another are selected from the group consisting of halogen, alkyl, trifluoromethyl, trifluoromethoxy, nitro, azido, amino, alkylamino, dialkylamino, hydroxyl, alkoxy, alkanoyloxy, R 8a denotes hydrogen or alkyl, R 9a denotes hydrogen, alkyl, hydroxyalkyl, carboxylalkyl or aminoalkyl, R 9b denotes hydrogen or alkyl, R 10a denotes hydrogen, alkyl or fluorine, R 10b denotes hydrogen or fluorine, R 11 denotes hydrogen or alkyl, R 12 denotes alkyl, alkenyl, cycloalkyl, cycloalkenyl, (cycloalkyl)alkyl, (cycloalkenyl)alkyl, (cycloalkyl)alkenyl (cycloalkenyl)alkenyl, where R 12 optionally can be substituted by 1, 2 or 3 substituents, which independently of one another are selected from the group consisting of halogen, hydroxyl, alkoxy, fluoroalkoxy, aryloxy, alkanoyloxy, alkoxycarbonyl, aminocarbonyl, alkylaminocarbonyl, dialkylaminocarbonyl, aminosulfonyl, alkylaminosulfonyl, dialkylaminosulfonyl, arylaminosulfonyl, heteroarylaminosulfonyl, heterocyclylaminosulfonyl, aminocarbonylamino, alkoxycarbonylamino, or R 6 and R 12 , together with the carbon atom to which they are bonded, form a cycloalkyl, which optionally can be substituted by 1 or 2 substituents, which independently of one another are selected from the group consisting of halogen, hydroxyl, alkoxy, R 13 denotes hydrogen or alkyl, A represents a heterocycle which optionally can be substituted by 1, 2 or 3 sub stituents, which independently of one another are selected from the group consisting of halogen, alkyl, trifluoromethyl, trifluoromethoxy, nitro, amino, alkylamino, dialkylamino, hydroxyl, alkoxy, alkanoyloxy, carboxyl, alkoxycarbonyl, azido, alkoxycarbonylamino, represents a single or double bond, or a pharmaceutically tolerable salt thereof.
