실험 절차

(R)-prop-1-en-2-yl 1-(3-fluoro-5-(1,1,2,2-tetrafluoroethoxy)phenyl)-1-(4-fluorophenyl)-2-phenylethylcarbamate (15 mg, 0.029 mmol) and 2-aminothiazole (8.2 mg, 0.082 mmol, 2.8 eq), and N-methylpyrrolidine (0.9 μl, 0.3 eq) were stirred in THF (0.3 mL) in a microwave vial. The reaction mixture was heated at 150° C. for 20 min under microwave irradiation. After cooling, the solvent was evaporated. The residue was purified by reverse phase HPLC (20-90% CH3CN in H2O with 0.1% TFA) to give pure (R)-1-(1-(3-fluoro-5-(1,1,2,2-tetrafluoroethoxy)phenyl)-1-(4-fluorophenyl)-2-phenylethyl)-3-(thiazol-2-yl)urea as white solids (6.5 mg, yield: 40.6%). 1H NMR (400 MHz, CDCl3-D) δ ppm 7.29 (m, 1H), 7.23-7.18 (m, 3H), 7.16 (t, J=8.0 Hz, 2H), 7.02 (t, J=8.5 Hz, 2H), 6.94-6.89 (m, 4H), 6.71 (d, J=6.82 Hz, 2H), 5.86 (tt, J=47.1, 2.9 Hz, 1H), 3.84-3.75 (m, 2H); LC-MS (ESI) 552.28 (M+H), retention time=4.12 min (10-90% MeOH in H2O with 0.1% TFA in a 4-min run).
