Patent ID: 8865707

Claim:
A compound of formula Ia, or a pharmaceutically acceptable salt thereof, wherein the phenyl ring may optionally have —N═ in place of the —(CH)═ at the unsubstituted position that is ortho to the methylene group in formula Ia; A 1 is phenyl, which is optionally substituted with 1-3 substituents independently selected from (a) halogen, (b) C 1-5 alkyl optionally substituted with 1-5 halogens and optionally 1 group —OH, (c) —OC 1-3 alkyl optionally substituted with 1-3 halogens, (d) C 2-4 alkenyl optionally substituted with 1-3 halogens, and (e) optionally one group selected from phenyl and C3-6cycloalkyl, said phenyl and cycloalkyl being optionally substituted with 1-3 substituents independently selected from halogen, —CO 2 H, —CO 2 C 1-3 alkyl optionally substituted with 1-3 halogens, C 1-3 alkyl optionally substituted with 1-3 halogens and optionally one —OH, and —OC 1-3 alkyl optionally substituted with 1-3 halogens; A 2 is phenyl optionally substituted with 1-3 groups independently selected from halogen, C 1-3 alkyl optionally substituted with 1-3 halogens, —OCH 3 and —OCF 3 ; each R a is independently selected from the group consisting of halogen, C 1-4 -alkyl optionally substituted with 1-3 halogens, C 2-3 alkenyl optionally substituted with 1-3 halogens, —OCH 3 , and —OCF 3 , wherein two R a groups on adjacent carbon atoms of the phenyl ring optionally may be joined to form a bridging moiety selected from —CH 2 CH 2 CH 2 —, —CH 2 CH 2 CH 2 CH 2 —, and —CH═CH—CH═CH—, thereby yielding a cyclopentyl, cyclohexyl, or phenyl ring fused to the phenyl ring, said cyclopentyl, cyclohexyl, and phenyl ring being optionally substituted with 1-2 groups independently selected from halogen, CH 3 , CF 3 , —OCH 3 , and —OCF 3 ; R 6 is C 1-3 alkyl optionally substituted with 1-3 halogens; p is an integer from 1-3; and n is an integer from 0-2.
