To a mixture of 4-(4-bromo-1H-imidazol-1-yl)-3-methoxybenzoic acid (1.90 g) in toluene (20 mL) and methanol (5 mL) was added trimethylsilyldiazomethane (2M hexane solution, 3.84 mL) at 0° C., and the mixture was stirred at room temperature for 2 hr. To the reaction mixture was added trimethylsilyldiazomethane (2M hexane solution, 0.96 mL), the mixture was stirred for 1 hr, and the solvent was evaporated under reduced pressure. The residue was recrystallized from ethyl acetate/hexane to give the title compound (1.32 g).
