Patent ID: 8076358

Claim:
A compound of formula (I) wherein R 1 is selected from the group consisting of C 1-4 alkyl, C 3-8 cycloalkyl, 5-6 membered heteroaryl, —(C 1-4 alkyl)-(5-6 membered heteroaryl), 5-6 membered heterocycloalkyl and —(C 1-4 alkyl)-5-6 membered heterocycloalkyl; R 2 is selected from the group consisting of hydrogen and halogen; L 1 is selected from the group consisting of —CH 2 —NR A —, —CH 2 CH 2 —NR A , —CH 2 —O— and —CH 2 —S—; wherein R A is selected from the group consisting of hydrogen, C 1-4 alkyl, —C(O)—C 1-4 alkyl, —C(O)O—C 1-4 alkyl and —SO 2 —C 1-4 alkyl; R 3 is selected from the group consisting of C 1-4 alkyl, carboxy substituted C 1-4 alkyl, C 4-8 cycloalkyl, —(C 1-4 alkyl)-C 4-8 cycloalkyl, partially unsaturated carbocyclyl, —(C 1-4 alkyl)-(partially unsaturated carbocyclyl), aryl, —(C 1-4 alkyl)-aryl, heteroaryl, —(C 1-4 alkyl)-heteroaryl, heterocycloalkyl and —(C 1-4 alkyl)-heterocycloalkyl; wherein the C 4-8 cycloalkyl, aryl, heteroaryl or heterocycloalkyl, whether alone or as part of a substituent group is optionally substituted with one or more substituents independently selected from the group consisting of halogen, hydroxy, carboxy, C 1-4 alkyl, fluorinated C 1-4 alkyl, —C 1-4 alkoxy-, fluorinated —C 1-4 alkoxy, —C 1-4 alkyl-OH, —C 1-4 alkyl-CO 2 H and phenyl; alternatively, R A and R 3 are taken together with the nitrogen atom to which they are bound to form a ring selected from the group consisting of 5 to 6 membered heteroaryl and 5 to 6 membered heterocycloalkyl; or a pharmaceutically acceptable salt thereof.
