To a methylene chloride solution of commercially available 2-(3-trifluoromethylphenyl)ethylamine (5.65 mmol) at 0° C. was added solid Proton sponge (5.65 mmol) then a 20% solution of phosgene in toluene (5.65 mmol). The solution was stirred at 25° C. for 1 hour and then washed with 1N HCl (40 mL). The methylene chloride was then dried with sodium sulfate and evaporated. 1H-NMR (CDCl3): 7.5 ppm (m, 4H); 3.6 ppm (t, 2H); 2.95 ppm (t, 2H).
