The compound was prepared according to Liu et al. J. Org. Chem. 2005, 70, 10135. 4-(1H-Imidazol-4-yl)-benzonitrile (75 mg, 0.44 mmol; prepared from 4-(2-bromo-acetyl)-benzonitrile using the method of Lynch et al. J. Am. Chem. Soc. 1994, 116, 11030), 4-bromo-1-chloro-2-iodobenzene (169 mg, 0.532 mmol), Cs2CO3 (577 mg, 1.77 mmol), CuI (3 mg, 0.013 mmol), 8-hydroxyquinoline (2 mg, 0.013 mmol), and DMF/H2O (2 mL; 10:1 solution) were combined in a 10 mL CEM Microwave reaction vessel fitted with magnetic stir bar and subjected to microwave irradiation at 150° C. for 30 min. The contents were then filtered and concentrated to dryness affording intermediate 5-bromo-2-chlorophenyl)-1H-imidazol-4-yl]-benzonitrile (68 mg, 43%).
