A solution composed of 2,2,2-trichloroethanol (30 g), N-(1,2,2,2-tetrachloroethyl) salicylamide (30 g) and toluene (200 ml) is refluxed until the generation of hydrogen chloride ceases (for about 5 to 8 hours). The reaction mixture is cooled to room temperature. The toluene layer is washed with water and dehydrated, and toluene is evaporated under reduced pressure to give the desired N-8 2,2,2-trichloro-1-(2,2,2-trichloroethoxy)-ethyl]salicylamide (37 g) represented by the foregoing formula as colorless crystals. mp. 111°-114° C.
