Patent ID: 8445690

Claim:
A compound of Formula (I) wherein X is CH or N; R 1 is C 1-4 alkyl, halo, or —C(O)—C 1-4 alkyl; wherein said C 1-4 alkyl may be substituted with halo; R 2 is halo, cyano, H, C 1-4 alkyl, C 2-4 alkenyl, C 1-4 alkoxy, —C(O)N(R 5 )(R 6 ), or hydroxyl; wherein said C 1-4 alkyl may be substituted with halo; R 3 is H, halo, —CN, or C 1-4 alkyl; and R 4 is heteroaryl, C 1-4 alkyl, cycloalkyl, or heterocyclyl; wherein said C 1-4 alkyl may be substituted with one to five groups, said groups independently selected from the group consisting of halo, —OR 5 , cycloalkyl, —N(R 5 )(R 6 ), —C(O)OR 5 , —C(O)N(R 5 )(R 6 ), —SO 2 N(R 5 )(R 6 ), —O—C 1-4 alkyl-OR 5 , heterocyclyl optionally substituted with halo, oxo or C 1-4 alkyl, and heteroaryl optionally substituted with C 1-4 alkyl; wherein said cycloalkyl may be substituted with one to three groups, said groups independently selected from the group consisting of halo, —C(O)OR 5 , and C 1-4 alkyl; wherein said heterocyclyl may be independently substituted with one to three groups, said groups independently selected from the group consisting of halo, C 1-4 alkyl, and —OR 5 ; wherein said C 1-4 alkyl may be substituted with —OR 5 ; wherein R 5 and R 6 are independently H or C 1-4 alkyl; or an optical isomer, enantiomer, diastereomer, cis-trans isomer, racemate, or pharmaceutically acceptable salt thereof.
