Into a 500-mL round-bottom flask, was placed (3-chloropropyl)(2,2,2-trifluoroethyl)amine (5 g, 28.48 mmol, 1.00 equiv), dichloromethane (300 mL), TEA (5.8 g, 57.32 mmol, 2.00 equiv), pyridine (0.5 mL). To this was added dropwise phenyl chloroformate (4.4 g, 28.10 mmol, 1.00 equiv) at 0° C. The resulting solution was stirred for 3 h at room temperature. The resulting mixture was washed with 2×100 mL of H2O. The resulting mixture was washed with 2×100 mL of brine. The mixture was dried over sodium sulfate. The resulting mixture was concentrated under vacuum. This resulted in 1.4 g (crude) of phenyl N-(3-chloropropyl)-N-(2,2,2-trifluoroethyl)carbamate as a colorless liquide.
