N-(2-(5-Chloro-2H-benzotriazol-2-yl)-1-cyano-1-methylethyl)-4-trifluoromethoxybenzamide (Ia) was tested against Haemonchus contortus in Mibgikuan gerbil at a dosage of 100 mg/kg, and showed 95% reduction in nematode infestation.    MECHANISM OF ACTION - None given.    ADMINISTRATION - Dosage is 0.5 mg to 5 g (preferably 1-500 mg). Administration is by oral, topical, dermal, subdermal or by injection routes.    SPECIFIC COMPOUNDS - 168 Compounds are disclosed as the aryloazol-2-yl-cyanoethylamine compounds (I), e.g. N-(2-(5-chloro-2H-benzotriazol-2-yl)-1-cyano-1-methylethyl)-4-trifluoromethoxybenzamide (Ia), N-(2-(5-chloro-2H-benzotriazol-2-yl)-1-cyano-1-methylethyl)-4-trifluoromethylbenzamide, N-(2-(5-chloro-2H-benzotriazol-2-yl)-1-cyano-1-methylethyl)-4-trifluoromethylthiobenzamide, N-(2-(5-chloro-2H-benzotriazol-2-yl)-1-cyano-1-methylethyl)-4-phenoxybenzamide and N-(2-(2H-benzotriazol-2-yl)-1-cyano-1-methylethyl)-4-trifluoromethoxybenzamide.    EXAMPLE - A mixture of 5-chloro-1H-benzotriazole (8 g), chloroacetone (6.5 ml), potassium carbonate (9.5 g) and potassium iodide (0.5 g) was stirred in acetone (90 ml) at room temperature for 48 hours. The reaction worked up to give 1-(5-chloro-2H-benzotriazol-2-yl)-propan-2-one. Ammonia was charged into methanol (50 ml) at -78 degrees C for 5 minutes. The solution was allowed to warm to room temperature and was then treated with sodium cyanide (0.7 g), ammonium chloride (0.9 g) and 1-(5-chloro-2H-benzotriazol-2-yl)-propan-2-one (2.25 g). The reaction mixture was stirred for 6 days at room temperature before concentrated under reduced pressure. The residue was taken into ethyl acetate, filtered and concentrated to give 2-amino-3-(5-chloro-2H-benzotriazol-2-yl)-2-methylpropionitrile (Ib). 4-Trifluoromethoxybenzoyl chloride (0.34 g) was added to a solution of the propionitrile (Ib) (0.3 g) in dry dichloromethane mixed with triethylamine (0.27 ml). The reaction mixture was stirred 48 hours at room temperature. After worked up, N-(2-(5-chloro-2H-benzotriazol-2-yl)-1-cyano-1-methylethyl)-4-trifluoromethoxybenzamide (Yield: 54%) was obtained.
