Procedure
A solution of methyl 3-fluoro-4-nitrobenzoate (4.66 g, 23.4 mmol), 3-trifluoromethoxyaniline (4.98 g, 28.1 mmol) and N,N-diisopropylethylamine (4.84 mL, 28.1 mmol) in dimethyl sulfoxide (30 mL) was stirred at 120° C. overnight. The reaction mixture was diluted with ethyl acetate, washed with water and saturated brine, dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The residue was recrystallized from hexane/tetrahydrofuran to give the title compound (2.90 g, yield 35%) as red crystals.
