Patent ID: 6858605

Claim:
A compound of formula (I), wherein: R 1 and R 2 independently of each other represent hydrogen or C 1 -C 3 alkyl, R 3 represents a substituted or unsubstituted 5- or 6-membered, aromatic, saturated or partially saturated heterocyclic ring having at least 2 heteroatoms selected from the group consisting of oxygen, sulfur and nitrogen, wherein the heterocyclic ring is optionally substituted with C 1 -C 5 alkyl, C 2 -C 3 alkenyl, C 3 -C 7 cycloalkyl, trifluoromethyl, C 1 -C 3 alkoxy, phenyl, formyl, carboxyl, C 2 -C 4 alkoxycarbonyl, halogen or oxo, the C 1 -C 5 alkyl or phenyl substituent being optionally substituted with halogen, C 1 -C 3 alkoxy, alkylated amino or acylated amino, provided that when the heterocyclic ring has 2 heteroatoms, then one of the heteroatoms is different from nitrogen; R 4 , R 5 , R 6 , R 7 and R 8 independently from each other represent hydrogen, halogen, C 1 -C 3 alkyl, nitro, or amino, wherein the amino is optionally substituted independently from each other with one or two C 1 -C 3 alkyl, C 2 -C 5 acyl, C 2 -C 5 alkoxycarbonyl, aminocarbonyl, or C 2 -C 5 alkylaminocarbonyl, R 9 represents C 1 -C 3 alkoxy or halogen, R 10 represents hydrogen or halogen or R 9 and R 10 together are C 1 -C 3 alkylenedioxy; or a stereoisomer or pharmaceutically acceptable acid addition salt thereof.
