Patent ID: 7459461

Claim:
A compound of Formula (Ic): wherein R 2 and R 3 are attached to a benzene ring and R 2 and R 3 together form a 6-membered carbocyclic ring fused to the benzene ring; thereby providing a multiple ring system; wherein the multiple ring system is selected from the group consisting of benzo fused cyclohexyl, benzo fused cyclohexenyl, and naphthalenyl, and, wherein the multiple ring system can optionally be substituted with one to four substituents independently selected from the group consisting of: da) C 1-4 alkyl optionally substituted on a terminal carbon atom with a substituent selected from the group consisting of: amino, substituted with two substituents independently selected from the group consisting of: hydrogen, and C 1-4 alkyl, (halo) 1-3 , and hydroxy; db) C 1-4 alkoxy optionally substituted on a terminal carbon atom with a substituent selected from the group consisting of: (halo) 1-3 and hydroxy; dc) amino substituted with two substituents independently selected from the group consisting of: hydrogen and C 1-4 alkyl; dd) halogen; de) hydroxy; and df) nitro; R 4 is selected from the group consisting of: C 1-4 alkyl, optionally substituted on a terminal carbon atom with aryl, and aryl, wherein aryl and the aryl portions of the substituted alkyl are optionally substituted with one to four substituents independently selected from the group consisting of: C 1-4 alkyl, amino, substituted with two substituents independently selected from the group consisting of: hydrogen, and C 1-4 alkyl, cyano, halogen, hydroxy, and (halo) 1-3 (C 1-8 )alkyl; R 5 is selected from the group consisting of: hydrogen, C 1-8 alkyl, optionally substituted on a terminal carbon atom with a substituent selected from the group consisting of: amino, substituted with two substituents independently selected from the group consisting of: hydrogen, and C 1-4 alkyl, (halo) 1-3 , and hydroxy and aryl, optionally substituted with one to four substituents independently selected from the group consisting of: C 1-8 alkyl, and halogen; R 6 is selected from the group consisting of: C 1-8 alkyl, aryl(C 1-8 )alkyl, C 1-8 alkoxy, aryl(C 1-8 )alkoxy, C 2-8 alkenyl, C 2-8 alkenyloxy, aryl(C 2-8 )alkenyl, aryl(C 2-8 )alkenyloxy, aryl, aryloxy and hydroxy; and racemates, enantiomers, diastereomers and salts thereof.
