Procedure
To a solution of (2-chloro-6-fluorophenyl)methanol (160.5 mg, 0.99 mmol) in THF (8 mL) was added sodium hydride (40 mg, 0.99 mmol) and the reaction was stirred at room temperature. After 25 minutes ethyl 1-(4-fluorophenyl)-2-iodo-1H-imidazole-5-carboxylate (38) (300 mg, 0.83 mmol) was added and the reaction was refluxed overnight. Water was added slowly and the solution was extracted with ethyl acetate. The combined organic layers were dried over sodium sulfate, filtered and concentrated in vacuo to afford ethyl 2-((2-chloro-6-fluorobenzyl)oxy)-1-(4-fluorophenyl)-1H-imidazole-5-carboxylate (39).
