Patent ID: 7947683

Claim:
A compound of formula (I) or a pharmaceutically acceptable salt thereof: wherein G is; p is 0 to 5; R 1 is independently selected from a group consisting of: halogen, hydroxy, cyano, C 1-4 alkyl haloC 1-4 alkyl, C 1-4 alkoxy, haloC 1-4 alkoxy, C 1-4 alkanoyl and SF 5 ; each R 2 is independently hydrogen, fluorine or C 1-4 alkyl; n is 2, 3, 4, or 5; R 3 is C 1-4 alkyl; R 4 is hydrogen, C 1-4 alkyl, benzyl, phenyl, heterocyclyl, a 5- or 6-membered heteroaromatic group, or a 8- to 11-membered bicyclic group, any of which groups is optionally substituted by 1, 2, 3 or 4 substituents selected from the group consisting of: halogen, cyano, C 1-4 alkyl, haloC 1-4 alkyl, C 1-4 alkoxy, haloC 1-4 alkoxy, C 1-4 alkanoyl and SF 5 ; or R 4 is a —SR 6 group; R 6 is C 1-4 alkyl or —CH 2 C 3-4 cycloalkyl; and when R 1 is chlorine and p is 1, such R 1 is not present in the ortho position with respect to the linking bond to the rest of the molecule; and when R 1 corresponds to R 5 , p is 1.
