실험 절차

To a solution of 643 mg (3.10 mmol) of 2-fluoro-5-trifluoromethylbenzaldehyde oxime in 5 mL of dimethyl formamide (DMF) was added 456 mg (3.41 mmol) of N-chlorosuccinimide (see K.-C. Liu, B. R. Shelton, and R. K. Howe, J. Org. Chem. 1980, 45, 3916). The reaction mixture was stirred at room temperature overnight, and then diluted with ethyl acetate. The ethyl acetate solution was washed with saturated sodium chloride and dried over magnesium sulfate. The drying agent was filtered off, and solvent was removed by rotoevaporation to give 675 mg (2.79 mmol) of pure white crystalline 2-fluoro-5-trifluoromethyl-N-hydroxybenzene-carboximidoyl chloride.
