실험 절차
A 0° C. solution of phosgene (20 wt % in toluene, 0.497 mL, 0.945 mmol) in DCM (4 mL) was treated slowly with a solution of 1-(2-(trifluoromethoxy)ethyl)imidazolidin-2-one (0.156 g, 0.787 mmol) and pyridine (0.127 mL, 1.575 mmol) in DCM (4 mL), stirred for 1 h at 0° C., then concentrated to dryness to afford 2-oxo-3-(2-(trifluoromethoxy)ethyl)imidazolidine-1-carbonyl chloride (100% yield assumed). MS [quenched in MeOH] (ESI) m/z: 257.1 (M+H+).
