Reaction Conditions

Reaction Steps

To a 50 mL round bottom flask attached with Vigreux column and magnetic stir bar was added 1-[1-(4-Bromo-phenyl)-2-(2-chloro-phenyl)-1H-imidazol-4-yl]-ethanone (270 mg, 719 μmol), 3-methylsulfonylphenyl boronic acid (220 mg, 1.08 mmol), PdCl2dppf (55 mg, 10 mol %), K2CO3 (300 mg, 2.16 mmol), 1,2-dimethoxyethane (11 mL) and H2O (1 mL). The reaction solution was allowed to stir at 70° C. for 14 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 NR4Cl (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 75% EtOAc to afford 170 mg (52% yield) of product. MS (ES): 451 [M+H]+, 473 [M+Na]+.
