Patent ID: 7074790

Claim:
A compound of the general formula (I) in which A denotes phenylene or pyridinylene, which can be substituted by 0 to 3 residues selected independently from the group consisting of halogen, (C 1 â€“C 4 )-alkyl, trifluoromethyl, cyano, nitro, (C 1 â€“C 4 )-alkoxy and trifluoromethoxy, R 1 denotes hydroxy or a group of the formula â€”NR 3 R 4 , â€”Xâ€”C(â•O)â€”OR 5 or â€”Xâ€”C(â•O)â€”NR 6 R 7 , wherein X denotes a bond, â€”CH 2 â€”, â€”CH 2 â€”CH 2 â€” or â€”CHâ•CHâ€”, R 3 and R 4 are independently selected from the group consisting of hydrogen, (C 1 â€“C 6 )-alkyl, (C 3 â€“C 7 )-cycloalkyl, (C 1 â€“C 6 )-alkanoyl and (C 6 â€“C 10 )-aroyl, wherein (C 1 â€“C 6 )-alkyl can be further substituted with 0 to 3 substituents selected independently from the group consisting of (C 3 â€“C 7 )-cycloalkyl and (C 6 â€“C 10 )-aryl, R 5 denotes hydrogen or (C 1 â€“C 6 )-alkyl, R 6 and R 7 are independently selected from the group consisting of hydrogen, (C 1 â€“C 6 )-alkyl, (C 3 â€“C 7 )-cycloalkyl and (C 6 â€“C 10 )-aryl, or together with the nitrogen atom to which they are attached form a 4- to 7-membered heterocyclic ring which may contain one additional ring heteroatom selected from N, O or S, R 2 denotes (C 3 â€“C 10 )-cycloalkyl, which is optionally substituted up to two times by residues selected independently from the group consisting of (C 1 â€“C 6 )-alkyl, (C 1 â€“C 6 )-alkoxy, hydroxy, halogen, trifluoromethyl and oxo.
