Reaction Steps

To a 50 mL round bottom flask attached with Vigreux column and magnetic stir bar was added 2-[1-(4-Bromo-phenyl)-2-(2-isopropyl-phenyl)-1H-imidazol-4-yl]-propan-2-ol (297 mg, 743 μmol), 3-methylsulfonylphenyl boronic acid (193 mg, 968 μmol), PdCl2 dppf (60 mg, 10 mol %), K2CO3 (310 mg, 2.23 mmol), 1,2-dimethoxyethane (14 mL) and H2O (4 mL). The reaction solution was allowed to stir at 80° C. for 2 hrs. The reaction solution was diluted with EtOAc (150 mL) and filtered through a Celite padded Buchner funnel to remove spent Pd. The filtrate was transferred to a separatory funnel and washed with aq NH4Cl (100 mL) and aq NaCl (100 mL). The organic phase was dried over Na2SO4, filtered, concentrated on the Rotavapor and chromatographed through a 25 g SiO2 column using a mobile phase gradient of 100% Hx to 90% EtOAc to afford 303 mg (86% yield) of the title compound. 1H NMR (400 MHz, DMSO-d6): δ 8.14 (s, 1H), 8.02 (d, 1H), 7.89 (d, 1H), 7.89 (d, 1H), 7.78 (d, 2H), 7.72 (t, 1H), 7.37-7.34 (m, 3H), 7.26 (d, 2H), 7.18-7.16 (m, 2H), 4.84 (s, 1H), 3.26 (s, 3H), 2.85 (sept, 1H), 1.50 (6H), 0.96 (d, 6H); MS (ES): 475.4 [M+H]+, 497.5 [M+Na].
