Patent ID: 8765959

Claim:
A compound of the formula I wherein Ar 1 is selected from the group consisting of: wherein the beforementioned phenylene group is optionally substituted with F, —CH 3 or —OCH 3 ; Ar 2 is phenylene optionally substituted with F or —OCH 3 ; L is selected from the group consisting of: straight-chain C 1-4 -alkylene, which may optionally be substituted with one or two C 1-3 -alkyl groups; R 1 is selected from the group consisting of: C 1-4 -alkyl-O—, C 3-4 -cycloalkyl-O— and C 3-4 -cycloalkyl-CH 2 —O—, wherein each alkyl and cycloalkyl may be optionally substituted with one or two F atoms; R 2 is selected from the group consisting of: H and C 1-3 -alkyl; and R 3 is selected from the group consisting of: C 1-3 -alkyl, —O—(C 1-2 -alkyl), C 3-5 -cycloalkyl, R N1 R N2 N—, morpholinyl, heteroaryl and heteroaryl-CH 2 —, wherein each alkyl may be optionally substituted with one to three F atoms or one CN, OH, —O—CH 3 and —S—CH 3 , and wherein each cycloalkyl may be optionally substituted with one CN, OH, or —CH 3 , and wherein each heteroaryl group is selected from the group consisting of pyrrolyl, imidazolyl, pyrazolyl, oxazoly, thiazolyl, benzimidazolyl and pyridinyl, and wherein each heteroaryl group may be optionally substituted with one or more substituents independently selected from the group consisting of phenyl, —CH 3 and —NH—C(═O)—CH 3 , and wherein R N1 is selected from the group consisting of H and C 1-3 -alkyl, and wherein R N2 is selected from the group consisting of H, C 1-3 -alkyl and pyridinyl; or a tautomer or pharmaceutically acceptable salt thereof.
