実験手順

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) (0.35 g, 0.77 mmol) in dichloromethane (2.6 mL) was added trifluoroacetic acid (0.060 mL, 0.78 mmol), and the solution was allowed to warm slowly to ambient temperature. After 18 hours, an additional amount of trifluoroacetic acid (0.060 mL, 0.78 mmol) was added. After 24 hours a third aliquot of trifluoroacetic acid (0.060 mL, 0.78 mmol) was added. After an additional 24 hours, the solution was concentrated to give the title compound as a tan solid (0.325 g, 88%): 1H NMR (400 MHz, DMSO-d6) δ 9.41 (s, 1H), 8.08 (dd, J=8.8, 2.6 Hz, 4H), 7.87 (s, 2H), 7.63 (d, J=8.3 Hz, 2H), 7.43 (d, J=8.3 Hz, 2H), 3.17-3.06 (m, 2H), 2.99-2.89 (m, 2H); ESIMS m/z 349 ([M+H]+).
