Patent ID: 8637671

Claim:
A compound of the formula Ib: and pharmaceutically acceptable salts thereof, wherein: Y is methylene; R 1 is selected from H, halogen, —OC 1-6 alkyl, and —C 1-6 alkyl; R 2 is selected from H, halogen, —C 1-6 alkyl, —OC 1-6 alkyl, —SC 1-6 alkyl, —S(O)C 1-6 alkyl, —S(O) 2 C 1-6 alkyl, —CN, aryl and heteroaryl; R 3 is selected from H, C 1-6 alkyl and benzyl optionally substituted on the phenyl portion with 1 to 3 halogen; R c is selected from halogen, NR f R g , SO 2 NR f R g , CN, C 1-6 alkoxy, C 1-6 alkyl, haloC 1-6 alkoxy, and haloC 1-6 alkyl; R d and R e are independently selected from hydrogen, C 1-6 alkyl, —C 1-6 alkyl-C 3-6 cycloalkyl, hydroxy, C 1-6 alkoxy, aryl optionally substituted with 1 to 3 groups independently selected from R c , and NR f R g ; or R d , R e together with the carbon atom to which they are both attached form a C 3-6 cycloalkyl optionally having a ring heteroatom selected from —O—, —S—, —N(C(O)R f )— and —N(R f )—, and optionally substituted with 1 to 3 C 1-3 alkyl groups; R f and R g are independently selected from hydrogen and C 1-3 alkyl; or R f , R g together with the atom to which they are both attached form a 3- to 6-membered ring.
