A suspension of 5-(3,4-difluoro-1H-pyrrol-1-yl)-2-nitrophenol (6.39 g), benzyl bromide (3.48 mL) and potassium carbonate (5.51 g) in DMF (60 mL) was stirred at room temperature overnight. The reaction mixture was poured into water, and the mixture was extracted with ethyl acetate. The extract was washed with water and saturated brine, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The residue was recrystallized from hexane/ethyl acetate to give the title compound (8.57 g).
