Patent ID: 8278306

Claim:
A compound having the formula: or a pharmaceutically acceptable salt thereof, wherein: R 1 is halogen —NR 2 , —OR, —SR, or a C 1-4 alkyl; R 2 is hydrogen or C 1-3 aliphatic; each R 3 is, independently, hydrogen or a C 1-4 alkyl; X 1 is N; T is a bond or a C 1 -C 6 alkylidene chain, wherein up to two methylene units of T are optionally and independently replaced by —NR′—, —S—, —O—, —C(O)NR′—, —NR′C(O)—, —NR′C(O)O—, —S(O) 2 NR′—, —NR′S(O) 2 —, —NR′C(O)NR′—, —OC(O)NR′—, or —NR′S(O) 2 NR′—; each R 5 is, independently, R a or halogen; n is 1 to 3; each occurrence of R a is, independently, hydrogen, an optionally substituted moiety selected from a C 1-4 alkyl group, a C 3-6 cycloalkyl group, a C 1-4 haloalkyl group, or a heterocyclic ring selected from morpholino, piperidinyl, or piperazinyl; each optionally substituted group or ring is optionally substituted with 1-5 substituents independently selected from C 1-4 alkyl, C 3-6 cycloalkyl, C 1-4 haloalkyl, halogen, or —OR″; each occurrence of R is, independently, hydrogen, a C 1-4 alkyl group, a C 3-6 cycloalkyl group, —(CH 2 ) 1-2 Ph, —CH═CHPh, or a C 1-4 haloalkyl group; each occurrence of R′ is, independently, hydrogen or a C 1-4 alkyl group; and each occurrence of R″ is, independently, hydrogen or a C 1-4 alkyl group.
