Reaction Steps

To tert-butyl 4-(1-(4-(trifluoromethoxy)phenyl)-1H-1,2,4-triazol-3-yl)phenethylcarbamate (C50) (0.021 g, 0.047 mmol) in anhydrous dimethylformamide (0.023 mL) at 0° C. was added sodium hydride (60% oil dispersion, 0.012 g, 0.30 mmol) and stirred in ice bath for 5 minutes. Iodomethane (0.013 g, 0.094 mmol) was added and the yellow solution immediately turned white. After 10 minutes, the reaction was quenched with water and extracted with dichloromethane. The organic layer was concentrated providing the title compound as a yellow oil (0.022 g, 97%): 1H NMR (400 MHz, CDCl3) δ 8.56 (s, 1H), 8.12 (d, J=8.2 Hz, 2H), 7.80 (d, J=9.0 Hz, 2H), 7.39 (dt, J=8.0, 1.0 Hz, 2H), 7.37-7.20 (m, 2H), 3.47 (s, 2H), 2.86 (s, 2H), 1.57 (s, 3H), 1.44 (d, J=13.7 Hz, 9H); 19F NMR (376 MHz, CDCl3) δ −58.03; ESIMS m/z 463 ([M+H]+).
