Reaction Conditions

Reaction Steps

To a mixture of 3 g of methyl 4-fluoro-2-methoxy-5-nitrobenzoate, 1.99 g of 2-(tetrahydro-2H-pyran-4-yl)-1H-imidazole, and 15 mL of N-ethylpyrrolidone was added 3.6 g of potassium carbonate, followed by stirring at 100° C. for 3 hours. To the reaction mixture were added water and ethyl acetate, 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 4.12 g of methyl 2-methoxy-5-nitro-4-[2-(tetrahydro-2H-pyran-4-yl)-1H-imidazol-1-yl]-benzoate.
