Patent ID: 8188113

Claim:
A compound, or a salt thereof, of the formula IIa: wherein Q1 is N and Q2 is CR3; wherein E1 is phenyl; wherein A is selected from the group consisting of phenyl, naphthyl, C3-C8carbocyclyl, —CHR4R8, pyridinyl, and benzothienyl; when A has one or more substitutable sp2-hybridized carbon atom, each respective sp2 hybridized carbon atom may be optionally substituted with a Z3 substituent; when A has one or more substitutable sp3-hybridized carbon atom, each respective sp3 hybridized carbon atom may be optionally substituted with a R3 substituent; each Z3 is independently and individually selected from the group consisting of H, methyl, ethyl, isopropyl, C3-C4 carbocyclyl, halogen, fluoroalkyl wherein the alkyl moiety can be partially or fully fluorinated, and cyano Z6 is (R3) 2 N—; wherein each R3 is independently and individually selected from the group consisting of H, C1-C6alkyl, branched C3-C7alkyl, and C3-C8carbocyclyl; each R4 is independently and individually selected from the group consisting of C1-C4alkyl, branched C3-C5alkyl, and C3-C5carbocyclyl; each R8 is independently and individually selected from the group consisting of C3-C8carbocyclyl, and Z3-substituted phenyl; R16 is independently and individually selected from the group consisting of hydrogen, methyl, ethyl, halogen, fluoroalkyl wherein the alkyl moiety can be partially or fully fluorinated, cyano, and C2-C3alkynyl; and t is 1-3.
