Reaction Conditions

Reaction Steps

To a 100 mL round bottom flask attached with condenser column and magnetic stir bar was added 1-(4-bromo-2-chlorophenyl)-2-(2-chlorophenyl)-N-(1-hydroxy-2-methylpropan-2-yl)-1H-imidazole-4-carboxamide (956 mg, 1.98 mmol), 3-methylsulfonylphenyl boronic acid (435 mg, 2.18 mmol), PdCl2dppf (150 mg, 10 mol %), K2CO3 (830 mg, 6.00 mmol), 1,2-dimethoxyethane (50 mL) and H2O (13 mL). The reaction solution was allowed to stir at 80° C. for 2.5 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 5% EtOAc to 100% EtOAc to afford 885 mg (80% yield) of the title compound.
