Claim:
A compound of formula: or a pharmaceutically acceptable salt therof, wheerein R 1 is optionally substituted with 1-3 moieties independently selected from the group consisting of —OH, —F, —Cl, —Br, —CO 2 H, —C(O)O—CH 3 , —CF 3 , —OCH 3 , —OCF 3 , —C 1 -C 6 alkyl, —CN, —C(O)NH 2 , —S—CF 3 , —SO 2 CH 3 , —NO 2 , —CF 3 CF 3 , —SO 2 CF 3 , —SO 2 CF 3 CF 3 , and —SO 2 NH 2 ; R 6 is —L 1 -A-(L 2 -B) 5 , wherein s is 0 or 1; L 1 is C 0 -C 3 -alkyl optionally mono- to per-halogenated; A is C 3 -C 6 -cycloalkyl, aryl, or heteroaryl; L 2 is a covalent bond or (C 0 -C 3 -hydrocarbyl)-X 1 —(C 0 -C 3 -hydrocarbyl), wherein X 1 is —C(O)—, —NH—, —NH—C(O)—, —C(O)—NH—, or heteroaryl; B is —H, C 3 -C 6 -cycloalkyl, aryl, or heteroaryl; or (L 2 -B) 2 togethre is —H or halo when s is 0; and A and B are independently optionally substituted with 1-3 moieties independently selected from the group consisting of halo, —CF 3 , —NO 2 , —CO 2 H, —CN, —C(O)—NH 2 , —SO 2 —NH 2 , or —C 0 -C 3 -hydrocarbyl-Y—(C 1 -C 3 -hydrocarbyl) wherein Y is a covalent bond, —O—C(O)—, —C(O)—, —O—, —S—, —SO 2 —, —C(O)—NH—, or —NH—C(O)—; and each alkyl moiety is optionally mono- to per-halogenated.
