Procedure

Under argon, first 3.34 g (7.90 mmol) of N-{2,2,2-trifluoro-1-[3-(trifluoromethyl)phenyl]ethyl}-acrylamide from Example 2, Stage 1, and then 2.49 g (7.90 mmol) of 4-iodo-2-(trifluoromethyl)benzoic acid (commercially available, CAS Registry Number: 954815-11-3), 0.206 g (7.90 mmol) of triphenylphosphine, 88.4 mg (0.39 mmol) of palladium(II) acetate and 13.5 g (133 mmol) of triethylamine were initially charged in 67 ml of N,N-dimethylformamide, and the reaction mixture was stirred at 100° C. for 5 hours. After addition of water, the solution was extracted with ethyl acetate, and then the organic phase was washed three times with saturated sodium chloride solution and dried over sodium sulphate. The solvent was distilled off under reduced pressure and the residue was chromatographed on silica gel with ethyl acetate.
