Procedure
A mixture of 2-bromo-2′-methoxy-acetophenone (514 mg), 4-fluorobenzamidine hydrochloride (392 mg) and potassium carbonate (930 mg) in acetonitrile (5 ml) was refluxed for 2 hours. After cooling, to the reaction mixture were added chloroform and water, the organic layer was collected and dried over anhydrous sodium sulfate, and the solvent was removed under reduced pressure. The resulting residue was recrystallized from methanol to obtain 2-(4-fluorophenyl)-4-(2-methoxyphenyl)imidazole (1.54 g) as pale yellowish crystal. This compound was treated with hydrogen chloride-ethanol solution to be converted into a hydrochloride salt form.
