Patent ID: 8653079

Claim:
A compound of formula (I): or a pharmaceutically acceptable salt thereof, wherein —X═Y— is selected from the group consisting of: (2) —CH═N—, or (3) —N═CH— R 1 is selected from the group consisting of (1) aryl, (2) a heteroaryl group which is a cyclic or polycyclic group, having from five to twelve ring atoms, said ring atoms selected from C, O, N or S, at least one of which is O, N or S, (3) a heterocyclic group, which is a non-aromatic cyclic or polycyclic group having from three to twelve ring atoms selected from C, O, N or S, at least one of which is O, N or S, (4) —C 1-6 alkyl, (5) —C 3-8 cycloalkyl, (6) —C 2-6 alkenyl wherein said aryl, heteroaryl, heterocyclic, alkyl, alkenyl and cycloalkyl R 1 moiety is optionally substituted with one or more (a) halogen, (b) hydroxy, (c) —O—C 1-6 alkyl, (d) —C 1-6 alkyl, and (e) cyano; R 2 is selected from the group consisting of (1) aryl, (2) a heteroaryl group which is a cyclic or polycyclic group, having from five to twelve ring atoms, said ring atoms selected from C, O, N or S, at least one of which is O, N or S, or (3) halogen, wherein said aryl or heteroaryl R 2 moiety is optionally substituted with one or more (a) halogen, (b) hydroxy, (c) —O—C 1-6 alkyl, (d) —C 1-6 alkyl, (e) —CN, (f) —NR A R B , (g) —NH(C═O)—C 1-6 alkyl, wherein R A and R B are selected from the group consisting of (i) hydrogen, or (ii) —C 1-6 alkyl, or R A and R B are linked together with the nitrogen to which they are both attached to form a 2-6 membered carbocyclic ring, wherein one or two of the ring carbon atoms is replaced by a nitrogen, oxygen or sulfur; R 3 is optionally present at one or more of the fused phenyl ring carbons, and each R 3 is selected from the group consisting of (1) —C 1-6 alkyl, (2) halogen, (3) cyano, and (4) —O—C 1-6 alkyl, wherein any alkyl R 3 moiety is optionally substituted with one or more halo.
