Patent ID: 8497271

Claim:
A compound of Formula (I) or a pharmaceutically acceptable salt thereof, wherein A is selected from phenyl and thienyl; R 1 is selected from C 2 -C 6 alkenyl; C 3 -C 6 alkoxy; C 3 -C 6 alkylsulfanyl; C 2 -C 6 alkynyl; C 3 -C 6 cycloalkyl-C 2 -C 4 alkenyl; C 3 -C 6 cycloalkyl-C 1 -C 3 alkoxy; C 3 -C 6 cycloalkyloxy; phenoxy optionally substituted with one C 1 -C 3 alkyl group; phenyl optionally substituted with one, two, or three groups independently selected from C 1 -C 3 alkoxy, C 1 -C 3 alkoxy-C 1 -C 3 alkyl, C 1 -C 3 alkyl, C 1 -C 3 alkylsulfonyl, cyano, halo, and halo-C 1 -C 3 alkyl; phenyl-C 1 -C 3 alkoxy wherein the phenyl part is optionally substituted with one or two groups independently selected from C 1 -C 3 alkyl and halo; and thienyl; R 2 is selected from hydrogen; C 1 -C 3 alkoxy; C 1 -C 3 alkyl; and halo; R 3 is selected from hydrogen and C 1 -C 3 alkoxy; R 4 is selected from C 1 -C 3 alkoxy-C 1 -C 3 alkyl; C 1 -C 6 alkyl; heterocyclyl; hydroxy-C 1 -C 3 alkyl; (R a R b N)—C 1 -C 3 alkyl; wherein denotes the point of attachment to the parent molecular moiety; R 5 is hydrogen; and R a and R b are independently selected from hydrogen and C 1 -C 3 alkyl; or R a and R b , together with the nitrogen atom to which they are attached, form a piperidinyl or piperazinyl ring wherein each ring is optionally substituted with one group selected from C 1 -C 3 alkyl and hydroxy-C 1 -C 3 alkyl.
