Title compds.[I; R = Me, Et; R1 = H, F, Cl, iodo, Br, Me, cyano, NO2 or CF3; R2 and R5 are independently H, F, Cl, Br, NO2, Me or CF3(only one of R2 and R5 is NO2); R3 and R4 are independently H, Me, F, Cl, Br or CF3 , useful as an intermediate in the prepn. of rodenticides, were prepd. from anilines(II) and 2-halo-5-nitrobenzotrifluoride. Thus, 8 g N-ethy1-2,4,6-trichloroaniline was treated with 3.5g NaH and 8.1 g 2-chloro-5-nitrobenzofluoride to give I.
