반응 단계

A mixture of 1.17 g (5.0 mmol) of N-acetyl-4-bromoaniline, 1.20 g (5.0 mmol) of N-fluoropyridinium triflate, and 50 ml of 1,1,2-trichloroethane was placed in a 100 ml 3-necked round bottomed flask equipped with a magnetic stirring bar, a thermometer, and a reflux condenser. The mixture was heated to 100° C. and allowed to react at that temperature for 20 hours. The mixture was then allowed to cool and the volatiles were removed by evaporation under reduced pressure. Analysis of the residue by standardized gas-liquid chromatography using a mass spectrometer detector indicated that the title product was present in 28 percent yield and that the balance of the N-acetyl-4-bromoaniline was still present as unreacted material.
