Procedure

To 374 μL of 2-fluoro-nitrobenzene in 2 mL of DMSO are added 962 μL of 4-trifluoromethoxyaniline (2 equivalents) and 636 mg of potassium tert-butanolate (1.6 equivalents). The whole is heated to 110° C. for 3 hrs. Once the reaction is completed, the medium taken up in a minimum of dichloromethane is hydrolyzed and then extracted. The organic phase is successively washed with water and then with a saturated solution of sodium chloride, dried on magnesium sulfate, filtered and concentrated under reduced pressure. A silica gel chromatography of the residue (cyclohexane and then cyclohexane/ethyl acetate: 99/1) allows 575 mg of the desired product to be isolated.
