Participants

Reaction Conditions

Reaction Steps

To a methylene chloride solution of commercially available 2-(trifluoromethoxy)benzyl amine (2.81 mmol) at 0° C. was added solid Proton sponge (2.81 mmol) then a 20% solution of phosgene in toluene (2.81 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 (d, 1H); 7.4 ppm (m, 2H); 7.3 ppm (d, 1H); 4.6 ppm (s, 2H).
