Patent ID: 7662956

Claim:
A compound of the formula (I) in which A is (C 6 -C 10 )-aryl or 5- to 10-membered heteroaryl, each of which may be substituted up to three times, identically or differently, by substituents selected from the group consisting of halogen, cyano, nitro, trifluoromethyl, trifluoromethoxy, (C 1 -C 6 )-alkyl, (C 2 -C 6 )-alkynyl and (C 1 -C 6 )-alkoxy, or is a group of the formula n is the number 1, 2 or 3, R 1 and R 2 are identical or different and are independently of one another hydrogen, halogen, cyano, nitro, trifluoromethyl, trifluoromethoxy, (C 1 -C 6 )-alkyl or (C 1 -C 6 )-alkoxy, R 3 is (C 1 -C 8 )-alkyl, (C 2 -C 8 )-alkenyl or (C 2 -C 8 )-alkynyl, each of which may be substituted by phenyl, (C 3 -C 8 )-cycloalkyl, hydroxy, (C 1 -C 6 )-alkoxy, (C 1 -C 6 )-acyloxy or amino, and R 4 is a group of the formula —OR 7 or —NR 8 R 9 , in which R 7 is hydrogen or (C 1 -C 6 )-alkyl, R 8 and R 9 are identical or different and are independently of one another hydrogen, (C 1 -C 6 )-alkyl or (C 3 -C 8 )-cycloalkyl, each of which may be substituted by substituents selected from the group consisting of carboxyl, (C 1 -C 6 )-alkoxycarbonyl, aminocarbonyl, and mono- and di-(C 1 -C 6 )-alkylaminocarbonyl, or R 8 and R 9 form together with the nitrogen atom to which they are bonded a 4- to 8-membered heterocycle which may comprise a further ring member selected from the series N—R 10 , O, S, SO and SO 2 and may be substituted by substituents selected from the group consisting of hydroxy, oxo, amino, (C 1 -C 6 )-alkyl, carboxyl, (C 1 -C 6 -alkoxycarbonyl, aminocarbonyl, and mono- and di-(C 1 -C 6 )-alkylaminocarbonyl, in which (C 1 -C 6 )-alkyl in turn may be substituted by substituents selected from the group consisting of hydroxy, amino, carboxyl, (C 1 -C 6 )-alkoxycarbonyl, aminocarbonyl, and mono- and di-(C 1 -C 6 )-alkylaminocarbonyl, and R 10 is hydrogen, (C 1 -C 4 )-alkyl, (C 1 -C 4 )-acyl or (C 1 -C 4 )-alkoxycarbonyl, or a salt thereof.
