Reaction Steps

Ethyl 1-(4-chlorophenyl)-2-(2,4-dimethylphenyl)-1H-imidazole-4-carboxylate (1.23 g, 3.47 mmol) was dissolved in EtOH (15 mL) and treated with N-bromosuccinimide (1.25 g, 7.02 mmol). The solution was stirred at rt for 3 h. Water was added. Extraction with dichloromethane, which was then washed with NaCl solution, gave an orange solid (1.94 g). Purification by chromatography over silica gel (20% EtOAc in hexane) afforded a light tan solid (1.028 g, 68%): 1H NMR (300 MHz, CDCl3) δ 7.35 (d, 2H), 7.03 (d, 2H), 7.00 (m, 1H), 6.86 (m, 2H), 4.44 (q, 2H), 2.26 (s, 3H), 2.10 (s, 3H), 1.43 (t, 3H); LC-MS m/z 433.1 (MH+), retention time 3.84 min (method 1).
