Procedure

A mixture of 2-(chloromethyl)-5-(2-(3,4-dichlorophenyl)propan-2-yl)-1-(4-fluorophenyl)-1H-imidazole (154 mg, 0.39 mmol), methyl 3-chloro-5-fluoro-4-hydroxybenzoate (118 mg 0.57 mmol), potassium carbonate (79 mg, 0.57 mmol), and 18-crown-6 (11 mg, 0.04 mmol) in CH3CN (4 mL) was heated 8 h at 60° C. After cooling, the reaction mixture was filtered, combined with water and DCM, and then extracted further with DCM. The combined extracts were washed with brine, dried over Na2SO4, and concentrated in vacuo. The material was purified by chromatography (silica, 0-70% EtOAc/Hex) to give methyl 3-chloro-4-((5-(2-(3,4-dichlorophenyl)propan-2-yl)-1-(4-fluorophenyl)-1H-imidazol-2-yl)methoxy)-5-fluorobenzoate as a white solid (150 mg, 68% yield). MS (EI) m/z 567.3 [M+H]+.
