Procedure
To a solution of 4-nitrophenyl chloroformate (4578 mg, 22715 μmol) and DIEA (2638 μL, 15143 μmol) in DCM (100 mL) at 0° C. was added 2,2,2-trifluoro-ethylamine (1500 μL, 15143 μmol). The resulting mixture was then stirred at 0° C. for 4 h and at RT for overnight. Then, the mixture was concentrated and a white precipitation was observed. The mixture was then filtered to give the title compound as a white solid, which was used in the next step without purification requirement.
