Procedure

Sodium hydride (containing mineral oil at 60%, 3 mg) was added to a solution of 2-bromoethyl 5-(4-fluorophenyl)-2-{(E)-2-[3-methoxy-4-(4-methyl-1H-imidazol-1-yl)phenyl]vinyl}-1H-imidazole-4-carboxylate (27 mg) in DMF (2 mL), and the reaction solution was stirred at room temperature for three hours. Ethyl acetate and saturated sodium bicarbonate water were added to the reaction solution, and the organic layer was separated. The resulting organic layer was dried over anhydrous magnesium sulfate and then concentrated under reduced pressure. The residue was purified by silica gel column chromatography (carrier: Chromatorex™ NH; elution solvent: ethyl acetate→ethyl acetate:methanol=5:1) to obtain 27 mg of the title compound. The property values of the compound are as follows.
