and
wherein said C1-6 alkyl, cycloalkyl, aryl, heterocyclyl or heteroaryl are optionally further substituted with one, two or three substituents independently selected from the group consisting of halo, aryl, —NO2, —CF3, —N(R20)(R22), —C(O)—R20, —C(O)—OR20, —C(O)—N(R20)(R22), —CN, —S(O)2—R20 and —O—R20;
each R10 is independently selected from the group consisting of halo, —NO2, —CN, —SF5, —Si(CH3)3, —O—R20, —S—R20, —C(O)—R20, —C(O)—OR20, —N(R20)(R22), —C(O)—N(R20)(R22), —N(R20)—C(O)—R22, —N(R20)—C(O)—OR22, —N(R20)—S(O)2—R26, —S(O)2—R20, —O—S(O)2—R20, —S(O)2—N(R20)(R22), C1-6 alkyl, C2-4 alkenyl, C2-4 alkynyl, cycloalkyl, aryl, heteroaryl and heterocyclyl;
wherein said C1-6 alkyl, C2-4 alkenyl, C2-4 alkynyl, cycloalkyl, aryl, heteroaryl or heterocyclyl are optionally substituted with one, two or three substituents independently selected from the group consisting of halo, —NO2, aryl, heterocyclyl, heteroaryl, C1-6 alkyl, C1-3 haloalkyl, cycloalkyl, —N(R20)(R22), —C(O)—R20, —C(O)—OR20, —C(O)—N(R20)(R22), —CN and —O—R20;
R17 is halo, —O—R20 or C1-6 alkyl;
R20 and R22 are in each instance independently selected from the group consisting of hydrogen, C1-6 alkyl, C2-6 alkenyl, C2-6 alkynyl, cycloalkyl, heterocyclyl, aryl and heteroaryl;
wherein the C1-6 alkyl, C2-6 alkenyl, C2-6 alkynyl, cycloalkyl, heterocyclyl, aryl and heteroaryl are optionally substituted with one, two or three substituents independently selected from the group consisting of hydroxyl, halo, C1-4 alkyl, acylamino, oxo, —NO2, —S(O)2R26, —CN, C1-3 alkoxy, —CF3, —OCF3, —OCH2CF3, —C(O)—NH2, aryl, cycloalkyl and heteroaryl;
and
wherein said heteroaryl is optionally further substituted with C1-4 alkyl or cycloalkyl;
or
when R20 and R22 are attached to a common nitrogen atom R20 and R22 may join to form a heterocyclic or heteroaryl ring which is then optionally substituted with one, two or three substituents independently selected from the group consisting of hydroxyl, halo, C1-4 alkyl, aralkyl, aryloxy, aralkyloxy, acylamino, —NO2, —S(O)2R26, —CN, C1-3 alkoxy, —CF3, —OCF3, aryl, heteroaryl and cycloalkyl;
