Patent ID: 7998990

Claim:
A compound of formula Ia wherein: R a* is hydrogen or C 1 -C 4 -alkyl; R b* is —(C 1 -C 4 -alkylene)-Y—C 1 -C 4 -fluoroalkyl; Y represents —CONH— or a five membered heteroaryl group R 2* is C 1 -C 4 -alkyl or halogen; R 3* is halo, —SO 2 —CH 3 , —SO 2 —CF 3 , —CO—NH 2 , —CO-di(C 1 -C 8 -alkyl)amino, or a 5- or 6-membered heterocyclic ring having one or more ring hetero atoms selected from the group consisting of oxygen, nitrogen and sulphur, that ring being optionally substituted by halo, cyano, oxo, hydroxy, carboxy, nitro, C 3 -C 8 -cycloalkyl, C 1 -C 8 -alkylcarbonyl, C 1 -C 8 -alkoxy optionally substituted by aminocarbonyl, or C 1 -C 8 -alkyl optionally substituted by hydroxy, C 1 -C 8 -alkoxy, C 1 -C 8 -alkylamino or di(C 1 -C 8 -alkyl)amino; R 4* is hydrogen, halo, —SO 2 —CH 3 , nitrile, C 1 -C 8 -haloalkyl, imidazolyl, C 1 -C 8 -alkyl, —NR 8* R 9* , or —SO 2 —NR 8* R 9* ; and R 5* is hydrogen, halogen or C 1 -C 8 -alkyl; R 8* and R 9* are independently hydrogen, amino, C 1 -C 8 -alkylamino, di(C 1 -C 8 -alkyl)amino, or C 1 -C 8 -alkyl optionally substituted by hydroxyl; or a pharmaceutically acceptable salt thereof.
