Procedure

4-Bromo-1-(4-trifluoromethoxyphenyl)-1H-imidazole (200 mg, 0.651 mmol), 5-acetyl-2-fluorophenylboronic acid (178 mg, 0.977 mmol), tetrakis(triphenylphosphine)palladium(0) (7 mg, 0.007 mmol), a 2 N aqueous solution of potassium carbonate (0.651 mL) and dioxane (8 mL) were combined and added to a microwave vessel. The reaction mixture was heated in the microwave with stiffing to 150° C. for 20 min. LC-MS indicated 88% anticipated product; TLC (1:1 hexanes:EtOAc) indicated the presence of starting material plus 3 other materials. EtOAc and water were added to the reaction mixture. The aqueous layer was extracted with EtOAc and the organic extracts were washed with brine, dried over MgSO4, and concentrated in vacuo. The crude product was purified by chromatography with gradient elution (100% hexanes to 100% EtOAc) resulting in 90 mg of an off-white solid. ESIMS 265.0 (M+H); mp 129° C.
