Procedure

To a room temperature solution of 2-(3,5-difluoro-phenyl)-pyrimidine (1.2 g, 6.24 mmole) in H2SO4 (3 mL) was added 90% HNO3 (0.375 mL, 9.37 mmoles) over 10 seconds via syringe. The resulting mixture was stirred at room temperature for 1 hour then poured into ice. The resulting heterogeneous mixture was then diluted with water, warmed to room temperature, and filtered. The solids were washed with water and dried in vacuo to afford the title compound (1.53 g, 100%) as a tan solid. 1H NMR (dmso-d6, 500 MHz): 8.92 (d, 2H); 8.67 (m, 1H); 7.94 (m, 1H); 7.65 (dd, 1H).
