Patent ID: 7820683

Claim:
A compound of the Formula I: wherein: R 1 is selected from hydrogen, hydroxy, (1-4C)alkoxy and (1-4C)alkoxy(1-4C)alkoxy; G 1 , G 2 , G 3 and G 4 are each, independently, selected from hydrogen and halogeno; X 1 is selected from SO 2 , CO, SO 2 N(R 6 ) and C(R 6 ) 2 , wherein each R 6 is, independently, selected from hydrogen and (1-4C)alkyl; Q 1 is aryl or heteroaryl, which aryl or heteroaryl group optionally bears one or more substituents independently selected from halogeno, cyano, (1-4C)alkoxy and (1-4C)alkyl; R 2 and R 3 , which may be the same or different, are selected from hydrogen, (2-4C)alkenyl, (2-4C)alkynyl and (1-4C)alkyl, which (1-4C)alkyl optionally bears one or more hydroxy substituents, or R 2 and R 3 together with the carbon atom to which they are attached form a cyclopropyl ring; R 4 and R 5 , which may be the same or different, are selected from hydrogen, (3-4C)alkenyl, (3-4C)alkynyl and (1-4C)alkyl, which (1-4C)alkyl optionally bears one or more substituents independently selected from halogeno, cyano, hydroxy, amino, (1-4C)alkylamino, di-[(1-4C)alkyl]amino and (1-4C)alkoxy, or R 4 and R 5 together with the nitrogen atom to which they are attached form a saturated 4, 5, 6 or 7 membered heterocyclic ring which optionally contains one or more additional heteroatoms independently selected from oxygen, S, SO, SO 2 and N(R 7 ), wherein R 7 is selected from hydrogen and (1-4C)alkyl, and wherein any heterocyclic ring formed by R 4 , R 5 and the nitrogen atom to which they are attached optionally bears one or more substituents independently selected from halogeno, cyano, hydroxy, (1-4C)alkyl and (1-4C)alkoxy, and wherein any heterocyclic ring formed by R 4 , R 5 and the nitrogen atom to which they are attached optionally bears 1 or 2 oxo or thioxo substituents; or a pharmaceutically acceptable salt thereof.
