Reaction Steps
To a mixture of 6.65 g of methyl 2-(methoxymethyl)-5-nitro-4-[2-(tetrahydrofuran-3-yl)-1H-imidazol-1-yl]benzoate, 980 mg of ammonium chloride, 33.0 mL of tetrahydrofuran, 66.0 mL of methanol, and 33.0 mL of water was added 4.8 g of reduced iron, followed by stirring at 70° C. for 4.5 hours. The insoluble matter was filtered through celite. The filtrate was concentrated, and water and ethyl acetate were added thereto, followed by extraction with ethyl acetate. The organic layer was washed with saturated brine and then dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure. The obtained residue was purified by silica gel column chromatography (chloroform/methanol) to obtain 5.30 g of methyl 5-amino-2-(methoxymethyl)-4-[2-(tetrahydrofuran-3-yl)-1H-imidazol-1-yl]benzoate as a brown solid.
