Patent ID: 8119669

Claim:
A compound of Formula (I) wherein X is S or O; n is 1-4 R 1 is halo, optionally substituted C 1-4 alkyl, optionally substituted C 1-4 alkoxy, or hydroxyl; R 2 is selected from halo substituted C 1-3 alkyl, cyano, halo, —C(O)NH 2 , and —C(O)O—C 1-4 alkyl, or alternatively R 2 is linked together to R 3 to form an aryl fused to the phenyl ring to which R 2 and R 3 are shown attached; R 3 is H, or alternatively R 3 is linked together to R 2 to form an aryl ring fused to the phenyl ring to which R 3 and R 2 are shown attached; R 4 is halo, cyano, halo substituted C 1-3 alkyl, —C≡CH, —C(O)O—C 1-4 alkyl, —C(O)NH 2 , or —S(O 2 )—C 1-4 alkyl; and R 5 and R 6 are independently H or optionally substituted C 1-4 alkyl, or alternatively R 5 and R 6 are linked together with the N atom to which they are attached to form an optionally substituted 5-9 membered N-containing heteroaryl or optionally substituted 5-7 membered N-containing heterocyclyl; or an optical isomer, enantiomer, diastereomer, cis-trans isomer, racemate, or pharmaceutically acceptable salt thereof.
