A mixture of 0.86 g of 4-bromophenol, 1.67 g of N-fluoro-2-chloro-6-(trichloromethyl)pyridinium fluoroborate, and 40 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 45° C. and allowed to react at that temperature for 23 hours under nitrogen. The mixture was then allowed to cool. Analysis by standardized gas-liquid chromatography using a mass spectrometer detector indicated that the title product was present in 74 percent conversion. The product identity was confirmed by its known 19F and 1H NMR spectra.
