Patent ID: 7166623

Claim:
A compound of formula (I): wherein when m is 0 to 4, R 1 is selected from C 1-6 alkyl, C 3-7 cycloalkyl, C 2-6 alkenyl, —SO 2 NR 4 R 5 , —CONR 4 R 5 and —COOR 4 ; and when m is 2 to 4, R 1 is additionally selected from C 1-6 alkoxy, hydroxy, NR 4 R 5 , —NR 4 SO 2 R 5 , —NR 4 SOR 5 , —NR 4 COR 5 , and —NR 4 CONR 4 R 5 ; R 2 is selected from hydrogen, C 1-6 alkyl and —(CH 2 ) n —C 3-7 cycloalkyl; R 4 and R 5 are independently selected from hydrogen, C 1-6 alkyl, heterocyclyl optionally substituted by C 1-4 alkyl; and phenyl wherein the phenyl is optionally substituted by up to two groups independently selected from C 1-6 alkoxy, C 1-6 alkyl and halogen; or R 4 and R 5 , together with the nitrogen atom to which they are bound, form a five- to six-membered heterocyclic or heteroaryl ring optionally containing one additional heteroatom selected from oxygen, sulfur and nitrogen, wherein the ring may be substituted by up to two C 1-6 alkyl groups; R 6 is selected from hydrogen and C 1-4 alkyl; U is selected from methyl and halogen; X and Y are each selected independently from hydrogen, methyl and halogen; m is selected from 0, 1, 2, 3 and 4 wherein each carbon atom of the resulting carbon chain may be optionally substituted with one or two groups selected independently from C 1-6 alkyl; n is selected from 0, 1, 2 and 3; r is selected from 0, 1 and 2; or a pharmaceutically acceptable salt or solvate thereof.
