摘要:
A compound of formula (I): ** Formula ** or a pharmaceutically acceptable salt thereof, wherein: X is O; Ar1 is (i) naphthyl; or (ii) naphthyl or phenyl, each of which is independently substituted with one to three Y; Y is F; Cl; CN; (C1-C8) alkyl, optionally substituted with (C3-C8) cycloalkyl or one to three F; cycloalkyl (C3-C8), optionally substituted with one to three F; NR7R8; (C1-C8) alkyloxy, optionally independently substituted with one to three R9; cycloalkyloxy (C3-C8); phenyl, optionally substituted independently with one to three R10; Het1 or Het2; wherein cycloalkyloxy (C3-C8) may optionally be fused to a phenyl ring or may be independently substituted with one to three R10; R1 is (C1-C6) alkyl or (C3-C8) cycloalkyl, each of which is optionally substituted with one to three F; R2, R3, R4 are independently H, F, Cl or -OCH3; R5 is H, CN, F, Cl or R6; R6 is a group selected from (C1-C6) alkyl and (C1-C6) alkyloxy, in which each group is optionally substituted, if valence permits, with one to five F; R7 and R8 are independently H; (C1-C8) alkyl, optionally independently substituted with one to three R11; cycloalkyl (C3-C8); or Het1 "bound to C"; wherein cycloalkyl (C3-C8) may optionally be fused to a phenyl ring or may be independently substituted with one to three R10; or R7 and R8, taken together with the nitrogen atom to which they are attached, form a bridged ring, saturated from 7 to 9 members; R9 is F; (C1-C6) alkyloxy; cycloalkyl (C3-C8), optionally substituted with one to three F; Het1; or phenyl, optionally independently substituted with one to three R6; R10 is F, Cl or R6; R11 is F; (C1-C6) alkyloxy; cycloalkyl (C3-C8), optionally substituted with one to three F; Het1 "bound to C"; or phenyl, optionally independently substituted with one to three R6; Het1 is a 3 to 8-membered saturated monoheterocycloalkyl comprising one or two ring members selected from -NR12- and -O-, said monoheterocycloalkyl being optionally substituted on a ring carbon atom
