실험 절차
To a mixture of 2,6-difluoroaniline (1.12 g) and potassium carbonate (1.8 g) in 50 mL dichloromethane was added bromoacetyl bromide (1.5 mL) and the mixture was stirred at room temperature for 17 h. Water was added and the mixture stirred for several hours then the phases were separated on a hydrophobic frit and the organic layer was evaporated. The crude product was purified by silica gel chromatography eluting with 0-100% EtOAc/cyclohexane to give the sub-titled compound (0.92 g) as a white solid.
