Patent ID: 8796328

Claim:
A compound of formula (I) or a pharmaceutically acceptable salt thereof wherein L is a bond or CH 2 , and is bound to any one of the carbon atom of the monocyclic ring containing X 1 ; X 1 is CH 2 or O; n is 1, 2, or 3; A is CH or N; m is 0, 1, 2, or 3; R x , at each occurrence, represents an optional substituent on any substitutable carbon atom of the ring containing A and each R x is independently alkyl, halogen, haloalkyl, OH, O(alkyl), O(haloalkyl), NH 2 , N(H)(alkyl), or N(alkyl) 2 ; p is 0, 1, or 2; R y , at each occurrence, represents an optional substituent on any substitutable carbon atom of the ring containing X 1 and each R y is independently alkyl or haloalkyl; two R y groups that are attached to the same carbon atom, together with said carbon atom to which they are attached, optionally form a C 3 -C 6 monocyclic cycloalkyl ring, wherein the monocyclic cyclcoalkyl ring is optionally substituted with 1, 2, or 3 substituents independently selected from the group consisting of alkyl, oxo, halogen, and haloalkyl; R z , at each occurrence, represents an optional substituent and is independently halogen, haloalkyl, alkyl, OH, O(alkyl), or O(haloalkyl); q is 0, 1, 2, or 3; R 1 is alkyl; R 2 is hydrogen or alkyl; and r is 1 or 2.
