• wherein
• R1 is halogen, cycloalkylalkoxy, haloalkoxy, alkylsulfonyl, alkylsulfinyl, halophenylalkyl, alkylsulfanyl, oxanylalkoxy, halophenyl or oxolanylalkoxy;
• R2 is halogen, cycloalkyl, haloalkyl, haloalkoxy, haloazetidinyl, cycloalkyloxy, halocycloalkyl, hydroxycycloalkyl, hydroxyazetidinyl, hydroxyoxetanyl or halooxetanyl;
• R3 is (alkyl)(oxo)pyrrolidinyl or —C(R4R5)—C(R6R7)—C(O)—R8;
