Claim:
A compound of Formula I or a pharmaceutically acceptable salt thereof, wherein A 1 is S, O, SO, or SO 2 ; R 5 is hydrogen, halogen or amino R 6 is hydrogen, halogen, or amino, cyano; R 7 is XR A where X is absent or —C≡C—, and R A is phenyl, or a monocyclic or bicyclic 5- to 10- membered bicyclic saturated, partially unsaturated, or aromatic heterocylic group containing at least one nitrogen atom and bound via a carbon atom; each of which R A is substituted with 0 to 5 substituents independently chosen from halogen, hydroxy, amino, cyano, C 1 -C 6 alkyl optionally substituted with amino, (C 1 -C 6 alkoxy)C 0 -C 4 alkyl, mono- and di-(C 1 -C 4 )alkylamino, ═NOR 10 , where R 10 is C 1 -C 4 alkyl, and —OR D , where R D is (C 2 -C 6 heterocycloalkyl)C 0 -C 2 alkyl; A 8 is CR 8 ; R 8 is hydrogen, C 1 -C 4 alkyl, C 1 -C 4 alkoxy; and R 9 is (C 3 -C 7 cycloalkyl)C 0 -C 4 alkyl or phenyl, each of which is substituted with 0 to 3 substituents independently chosen from halogen.
