実験手順

A mixture of 3,4-difluoronitrobenzene (1.00 mL, 9.03 mmol), imidazole (0.615 g, 9.04 mmol) and K2CO3 (2.50 g, 18.1 mmol) in DMF (10 mL) was stirred at room temperature overnight. Water (20 mL) was added to induce precipitation. The precipitate was collected, dried on vacuum to give 1-(2-fluoro-4-nitrophenyl)-1H-imidazole as a solid (1.81 g). MS 208.2 (M+H)
