Several 2-alkoxycarbonyltrifluoromethanesulfonanilides were prepared to examine their miticidal activity. 4-Halo-2-alkoxycarbonyltrifluoromethanesulfonanilides in particular showed good miticidal activity against Tyrophagus putrescentiae (Tp), Dermatophagoides farinae (Dp) and Chelacaropsis moorei (Cm). Amidoflumet (methyl 5-chloro-2-[(trifluoromethyl)sulfonyl]aminobenzoate) was selected and has been developed as a new miticide for house dust mites.
