実験手順

To a solution of 5-bromo-1(2,6-dichloro-4-trifluoromethylphenyl)-3-cyano-4-trifluoromethylsulfonylpyrazole (5.0 g, 9.7 mmol) in 1,4-dioxane (20 ml) and N,N-dimethylformamide (20 ml) was added 3-ethylthiopropylamine (2.306 g, 19.3 mmol) and potassium carbonate (2.7 g, 19.3 mmol). The resulting mixture was stirred at 20° C. for 2.75 hours, left to stand overnight, then poured into a mixture of water and dichloromethane. The organic phase was washed with water, dried (sodium sulfate), evaporated and chromatographed on silica gel, eluting with heptane-ethyl acetate (4:1) to give 1-(2,6-dichloro-4-trifluoromethylphenyl)-3-cyano-5-(3-ethylthiopropylamino)-4-trifluoromethylsulfonylpyrazole as a yellow solid (Compound number 1-14, 4.79 g, 86% yield), mp 80° C.
