実験手順

0.2 g (4.0 mmoles) of sodium hydroxide and 1 ml of water were added to a solution of 0.25 g (4.0 mmoles) of ethanethiol dissolved in 10 ml of N,N-dimethylformamide. The mixture was stirred at room temperature for 30 minutes. Thereto was added a solution of 0.5 g (1.4 mmoles) of 5,5-dimethyl-3-(5-fluoro-1-phenyl-3-trifluoromethyl-1H-pyrazol-4-ylmethylthio)-2-isoxazoline dissolved in 5 ml of N,N-dimethylformamide. The resulting mixture was stirred for 1 hour to give rise to a reaction. After the completion of the reaction, the reaction mixture was poured into water, followed by extraction with ethyl acetate. The resulting organic layer was washed with an aqueous sodium chloride solution and then dried over anhydrous magnesium sulfate. The resulting solution was subjected to vacuum distillation to remove the solvent contained therein, to obtain 0.6 g (yield: 100%) of 5,5-dimethyl-3-(5-ethylthio-1-phenyl-3-trifluoromethyl-1H-pyrazol-4-ylmethylthio)-2-isoxazoline.
