Patent ID: 8258135

Claim:
A compound of formula (I): wherein R 1 is selected from the group consisting of (1) cyano, (2) —C(═O)—OR 4A , (3) —C(═O)—R 4A , (4) —OH, and (5) phenyl; R 2 is selected from the group consisting of (1) —(CH 2 ) n -aryl, and (2) heteroaryl, wherein said aryl or heteroaryl moiety is optionally substituted with one or more (a) halogen, (b) hydroxy, (c) —O—C 1-6 alkyl, (d) —C 1-6 alkyl, (e) —C 2-6 alkenyl (f) —S(O) m —R 4A , (g) —C 2-6 alkynyl, and (h) —N(R 4A R 4B ); R 3 is selected from the group consisting of (1) hydrogen, (2) —C 1-6 alkyl, and (3) —CH 2 -aryl, wherein said R 3 alkyl or aryl moiety is optionally substituted with one or more (a) halogen, (b) cyano, and (c) —O—C 1-6 alkyl, wherein said alkyl is optionally substituted with one or more halo; R 4A and R 4B are each independently selected from the group consisting of (1) hydrogen, (2) —C 1-6 alkyl, (3) —(CH 2 ) n -aryl, wherein said R 4A or R 4B alkyl or aryl moiety is optionally substituted with one or more (a) halogen, (b) cyano, and (c) —O—C 1-6 alkyl, wherein said alkyl is optionally substituted with one or more halo; R 6 is optionally present at one or more of the ring carbon atoms, and each R 6 is independently selected from the group consisting of (1) halogen, (2) —C 1-6 alkyl, and (3) —(CH 2 ) n -aryl, wherein said R 6 alkyl or aryl moiety is optionally substituted with one or more (a) halogen, (b) cyano, and (c) —O—C 1-6 alkyl, wherein said alkyl is optionally substituted with one or more halo; m is 0, 1 or 2; n is 0, 1 or 2; or a pharmaceutically acceptable salt thereof.
