실험 절차

To a stirred and cooled (0° C.) solution of tert-butyl 4-(1-(4-(trifluoromethoxy)phenyl)-1H-1,2,4-triazol-3-yl)phenethylcarbamate (C50) (0.10 g, 0.22 mmol) in dichloromethane (1.6 mL) was added trifluoroacetic acid (0.19 mL, 0.25 mmol), and the solution was allowed to warm slowly to ambient temperature and stirred overnight. The reaction mixture was concentrated, taken up in hexanes, and concentrated until a solid was obtained. The solid was dissolved in dichloromethane and washed with saturated sodium bicarbonate. The aqueous layer was extracted with dichloromethane (2×). The combined organic layers were washed with saturated sodium bicarbonate. The organic layers were dried over magnesium sulfate, filtered, and concentrated to give the title compound as a white solid (0.075 g, 97%): 1H NMR (400 MHz, CDCl3) δ 8.56 (s, 1H), 8.18-8.07 (m, 2H), 7.83-7.74 (m, 2H), 7.41-7.29 (m, 4H), 3.02 (t, J=6.8 Hz, 2H), 2.81 (t, J=6.8 Hz, 2H), 1.45-1.29 (m, 2H); 19F NMR (376 MHz, CDCl3) δ −58.04.
