실험 절차

3-Bromophenyl isocyanate (21.12 g, 107 mmol) was added slowly to a stirred solution of 2,2,2-trifluoroethyl amine (40 ml, 0.5 mol) in THF (100 mL) at 0° C. under N2, rinsing with THF (25 mL). The reaction was allowed to warm slowly to RT and kept at this temperature for 16 hours. The volatiles were removed under reduced pressure to give the title compound (31.6 g) as a solid. 1H NMR (400 MHz, DMSO-d6) δ 8.94 (1H, s), 7.80 (1H, t), 7.31-7.24 (1H, m), 7.20 (1H, t), 7.16-7.08 (1H, m), 6.83 (1H, bt), 3.98-3.85 (2H, m).
