Patent ID: 8247599

Claim:
A compound of Formula (Ia): wherein R 7 is selected from the group consisting of hydrogen, C 1-8 alkyl and C 2-8 alkenyl; and, R 8 is cycloalkyl; wherein the cycloalkyl is optionally substituted with one to four substituents independently selected from the group consisting of: ba) C 1-8 alkyl optionally substituted on a terminal carbon atom with a substituent selected from the group consisting of amino (with two substituents independently selected from the group consisting of hydrogen and C 1-8 alkyl), (halo) 1-3 and hydroxy; bb) C 1-8 alkoxy optionally substituted on a terminal carbon atom with a substituent selected from the group consisting of carboxyl, (halo) 1-3 and hydroxy; bc) carbonyl substituted with a substituent selected from the group consisting of C 1-8 alkyl, aryl, aryl(C 1-8 )alkyl and aryl(C 2-8 )alkenyl; bd) aryl; be) amino substituted with two substituents independently selected from the group consisting of hydrogen and C 1-8 alkyl; bf) cyano; bg) halogen; bh) hydroxy; bi) nitro; and bj) sulfonyl substituted with a substituent selected from the group consisting of C 1-8 alkyl, aryl, aryl(C 1-8 )alkyl and aryl(C 2-8 )alkenyl; wherein the bd) aryl substituents and the aryl portions of the bc) substituent are optionally substituted with one to four substituents independently selected from the group consisting of 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 1-8 alkyl), (halo) 1-3 and hydroxy), C 1-4 alkoxy (optionally substituted on a terminal carbon atom with a substituent selected from the group consisting of (halo) 1-3 ), amino (substituted with two substituents independently selected from the group consisting of hydrogen and C 1-4 alkyl), halogen, hydroxy and nitro; and, racemates, enantiomers, diastereomers and pharmaceutically acceptable salts thereof.
