Reaction Steps
To a solution of 1-(4-bromo-2-nitro phenyl)-1H-imidazole (500 mg) in methylene chloride (10 mL) and methanol (10 mL) at 0° C. nickel hexahydrate (22.0 mg) and sodium borohydride (177 mg) were added one by one, and the reaction solution was agitated for 20 minutes. Water and ethyl acetate were added to the reaction solution, and the organic layer was partitioned. After the obtained organic layer was washed with a saturated saline solution, it was dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The residue was purified by silica gel chromatography (Carrier: Chromatorex™ NH; elution solvent: hexane:ethyl acetate=1:1->ethyl acetate), and 431 mg of the title compound was obtained. The physical properties of the compound are as follows.
