Reaction Steps

A mixture of 2-[2-(4-bromo-2-chlorophenyl)-5-chloro-1-(2,6-dichlorophenyl)-1H-imidazol-4-yl]-propan-2-ol (184 mg, 0.37 mmol), 3-methanesulfonyl-phenylboronic acid (90 mg, 0.45 mmol), K2CO3 (0.15 g, 1.1 mmol), Cl2Pd(dppf).DCM (15 mg, 5 mol %) and H2O (0.2 mL) in DME (2 mL) was sparged with Argon for 5 min and then heated at 60° C. as a sealed flask. After 70 min the reaction mixture was allowed to cool to ambient temperature, filtered (Celite™) and the filter agent rinsed with EtOAc. The combined filtrates were concentrated under reduced pressure and purified by chromatography (silica, EtOAc/Hex, 20:80 to 60:40) to give the title compound (165 mg, 78%) as a white solid. 1H-NMR (DCM-d2): δ 8.08 (m, 1H), 7.93 (m, 1H), 7.84 (m, 1H), 7.73 (d, 1H), 7.67 (m, 1H), 7.33-7.47 (m, 5H), 3.42 (br s, 1H), 3.06 (s, 3H), 1.68 (s, 61-1); MS (ES): 591, 593, 595 [M+Na]+.
