Patent ID: 7482472

Claim:
A compound of the formula (I) in which R 1 and R 2 together represent O and R 3 and R 4 together represent O, or R 1 represents hydrogen, hydroxy or (C 1 -C 4 )-alkoxy, R 2 represents hydrogen and R 3 and R 4 together represent O, or R 1 and R 2 together represent O, R 3 represents hydrogen, hydroxy or (C 1 -C 4 )-alkoxy and R 4 represents hydrogen, R 5 represents halogen, trifluoromethyl or methyl, A represents (C 1 -C 4 )-alkanediyl which may be substituted by hydroxy or (C 1 -C 4 )-alkoxy, a represents 0 or 1, B represents a group in which R 6 represents hydrogen or (C 1 -C 4 )-alkyl, b represents 0 or 1, D represents piperazine, which may be mono- or disubstituted, independently of one another, by hydroxy, carbamoyl, (C 1 -C 4 )-alkanoyl, (C 3 -C 7 )-cycloalkanoyl, (C 3 -C 7 )-cycloalkyl, 5- to 10-membered heterocyclyl, (C 1 -C 4 )-alkoxycarbonyl, (C 1 -C 6 )-alkyl, which for its part may be substituted by hydroxy, cyano, (C 1 -C 4 )-alkoxy, mono- or di-(C 1 -C 6 )-alkylamino, mono- or di-(C 1 -C 6 )-alkylaminocarbonyl, 5- to 10-membered heterocyclyl, 5- or 6-membered heterocyclylcarbonyl or 5- to 10-membered heteroaryl, (C 6 -C 10 )-aryl, which for its part may be substituted by halogen, trifluoromethyl, nitro, (C 1 -C 4 )-alkyl or (C 1 -C 4 )-alkoxy, 5- to 10-membered heteroaryl, which for its part may be substituted by cyano, amino or (C 1 -C 4 )-alkyl, or 5- to 10-membered heteroarylcarbonyl, or a salt thereof.
