Patent ID: 8022215

Claim:
A compound of formula (I): or a pharmaceutically acceptable salt thereof, wherein Q is selected from the group consisting of (2) —CH 2 CH 2 —; R 1 and R 2 are each selected from the group consisting of (1) hydrogen, (2) hydroxy, (3) —C 1-6 alkyl, (4) —OC 1-6 alkyl, (5) —C 1-3 alkyl-C 6-10 aryl, or (6) —N(R 7 R 8 ), wherein any R 1 or R 2 alkyl or aryl moiety is optionally substituted with one or more halogen, or R 1 and R 2 together form the group ═O; R 3 and R 4 are each selected from the group consisting of (1) hydrogen, (2) hydroxy, (3) —C 1-6 alkyl, or (4) —OC 1-6 alkyl, or R 3 and R 4 together form the group ═O; R 5 is selected from the group consisting of (1) —CH 2 —C 6-10 aryl, (2) —C 2-4 alkenyl-C 6-10 aryl, or wherein any R 5 aryl moiety is optionally substituted with one or more (a) halogen, (b) hydroxy, (c) cyano, (d) —(CH 2 ) q -aryl, (e) —O—(CH 2 ) q -aryl, (f) —C 1-6 alkyl, (g) —OC 1-6 alkyl, (h) heteroaryl, wherein said heteroaryl is an aromatic cyclic group having from 5 to 12 cyclic atoms, said cyclic atoms selected from carbon, nitrogen, oxygen or sulfur, (i) —N(R 7 R 8 ), and wherein said alkyl, aryl or heteroaryl moiety is optionally substituted with one or more (i) halogen, (ii) hydroxy, (iii) cyano, (iv) —C 1-6 alkyl, or (v) —OC 1-6 alkyl, R 6 is selected from the group consisting of (1) hydrogen, (2) —C 1-6 alkyl, and (3) —CH 2 -aryl, wherein any 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; R 7 and R 8 are each selected from the group consisting of (1) hydrogen, (2) —C 1-6 alkyl, (3) —C 1-3 alkyl-C 6-10 aryl, and any R 7 and R 8 alkyl or aryl moiety is optionally substituted with one or more halogen, or R 7 and R 8 and the nitrogen atom to which they are both bonded are linked together to form a 5- or 6-membered ring; and q is 0 or 1.
