Patent ID: 7202243

Claim:
A compound of the formula in which R 1 denotes hydrogen or C 1 –C 6 -alkyl, R 5 denotes hydrogen, formyl, C 1 –C 6 -alkyl, (C 1 –C 6 -alkyl)carbonyl, C 1 –C 6 -alkylsulfonyl, (C 3 –C 8 -cycloalkyl)carbonyl or (3- to 8-membered heterocyclyl)carbonyl, where alkylcarbonyl can be substituted by up to 3 substituents—independently of one another selected from the group consisting of halogen, hydroxyl, amino, carboxyl, C 1 –C 6 -alkoxy, C 6 –C 10 -aryl, C 1 –C 6 -alkylamino and a 3- to 8-membered heterocyclyl substituted by up to 3 C 1 –C 3 -alkyl substituents— or R 1 and R 5 , together with the nitrogen atom to which they are bonded, denote a 5- to 8-membered heterocycle, which can be substituted by up to 3 substituents—independently of one another selected from the group consisting of halogen, hydroxyl, C 1 –C 6 -alkyl, C 1 –C 6 -alkoxy, C 6 –C 10 -aryl, amino and C 1 –C 6 -alkylamino R 2 denotes C 1 –C 6 -alkyl or C 3 –C 4 -cycloalkyl, R 3 denotes methyl, A denotes an oxygen atom or NH, and R 4 denotes C 6 –C 10 -aryl, which can be substituted by up to 3 substituents—independently of one another selected from the group consisting of halogen, formyl, carboxyl, carbamoyl, cyano, hydroxyl, trifluoromethyl, trifluoromethoxy, nitro, C 1 –C 6 -alkyl, C 1 –C 6 -alkoxy, 1,3-dioxapropan-1,3-diyl, C 1 –C 6 -alkylthio and —NR 6 R 7 —, in which R 6 and R 7 independently of one another represent hydrogen, C 1 –C 6 -alkyl or (C 1 –C 6 -alkyl)carbonyl, or salt thereof.
