Claim:
A compound of formula I: X is CH; Y is halo, trifluorophenoxy, or tetrafluorophenoxy; R 2 is C 1-6 straight chained or branched alkyl; R 3 is hydrogen, halo, OCF 3 , CN, or CF 3 ; and R 4 is hydrogen, halo, OCF 3 , SR, CN, CF 3 , Ar, or T—Ar; wherein: T is O or S; R is a C 1-6 straight chained or branched alkyl; Ar is a phenyl ring optionally substituted with 1-3 groups selected from halo, CH 3 , CF 3 , CN, OMe, OCF 3 , and NR 5 R 6 ; and R 5 and R 6 each is independently H or C 1-6 straight chained or branched alkyl, or R 5 and R 6 , taken together, form a 5-7 membered ring optionally containing up to 3 heteroatoms selected from O, S, NH, and N(C 1-6 -straight chained or branched alkyl); provided that when Y is halo, then both, R 3 and R 4 , are not simultaneously hydrogen.
