To a solution of 1H-Imidazole-4-carbonitrile (300 mg, 3.22 mmol) and 4-Fluoro-3-methoxynitrobenzene (552 mg, 3.22 mmol) in DMF (Volume: 6446 μl) was added K2CO3 (891 mg, 6.45 mmol). The resulting mixture was brought to 120° C. and stirred overnight. The reaction mixture was diluted with EtOAc (20 mL), washed with water (2×10 mL), brine (10 mL), dried over MgSO4, filtered and concentrated in vacuo to give 1-(2-methoxy-4-nitrophenyl)-1H-imidazole-4-carbonitrile (698 mg, 2.86 mmol, 89% yield). LC-MS (M+H)+=245.0. 1H NMR (500 MHz, MeOD) δ ppm 8.30-8.34 (1H), 8.19-8.23 (1H), 8.09-8.12 (1H), 8.00-8.05 (1H), 7.71-7.79 (1H), 4.02-4.10 (3H).
