Claim:
A compound of general formula [I]: wherein: R 1 and R 2 are each independently selected from the group consisting of: (1) optionally hydroxyl- or halogen-substituted lower alkyl, (2) optionally R 9 -substituted 3 to 6-membered cycloalkyl, and (3) optionally R 9 -substituted 4 to 6-membered heterocycloalkyl, or (4) R 1 and R 2 together form a 4 to 11-membered crosslinking, non-crosslinking or spiro ring aliphatic nitrogen-containing heterocycle, with the nitrogen atom to which they bind, one or two optional hydrogen atoms in the aliphatic nitrogen-containing heterocycle being optionally substituted with R 9 ; R 3 , R 4 , R 6 and R 7 are each independently selected from the group consisting of: (1) hydrogen, (2) hydroxyl, (3) halogen, and (4) optionally halogen-substituted lower alkyl; R 5 stands for: (1) hydrogen, or (2) optionally halogen-substituted lower alkyl; each R 8 is independently selected from the group consisting of: (1) halogen, (2) lower alkyl, and (3) lower alkyloxy; R 9 is selected from the group consisting of hydroxyl, amino, mono-lower alkylamino, di-lower alkylamino, optionally hydroxyl- or halogen-substituted lower alkyl, (lower alkyloxycarbonyl)amino, lower alkyloxycarbonyl-(lower alkyl)amino, lower alkylcarbonylamino, lower alkylcarbonyl(lower alkyl)amino, mono-lower alkylcarbamoyl-(lower alkyl)amino, di-lower alkylcarbamoyl(lower alkyl)amino, lower alkylsulfonylamino, lower alkylsulfonyl(lower alkyl)amino, oxo and 2-oxopyrrolidinyl; and n is 0, 1, 2, 3 or 4; or a pharmaceutically acceptable salt thereof.
