Procedure

6,6-dichloropyrimidine (1.000 g, 7 mmol) was dissolved in N,N-dimethylformamide (5 ml, 7 mmol), then 2-fluoro-4-nitrophenol (1 g, 7 mmol) was added into the mixture. Then Cesium Carbonate (2 g, 10 mmol) was added into the mixture with stirring. The mixture was stirred at ambient temperature under nitrogen overnight. The progress of the reaction was monitored by LC/MS, which had confirmed completion. Then diluted the mixture with water was stirred an additional 3 hours. The precipitate was collected by filtration and washed with hexanes. The solid was dried in a reduced-pressure oven overnight to give the desired product 4-chloro-6-(2-fluoro-4-nitrophenoxy)pyrimidine (1.500 g, 6 mmol, 83% yield) as a yellow solid. MS (ESI pos. ion) m/z: 270 (MH+). Calc'd exact mass for C10H5ClFN3O3: 269. 1HNMR (300 MHz, CDCl3): 7.14 (s, 1H), 7.43 (s, 1H), 8.14 (s, 2H), 8.55 (s, 1H).
