Reaction Steps

The title compound was prepared according to the procedure described in Example-108 by using 5-(5-(aminomethyl)-2-chloro-4-fluorophenyl)-2-(6-(trifluoromethyl)pyridin-3-yl)-2H-1,2,4-triazol-3(4H)-one (Intermediate-82, 0.300 g), pivaloyl chloride (0.3 mL), TEA (2.0 mL), dry THF (10 mL) to afford 0.050 g of the desired product. 1H NMR (300 MHz, CDCl3): δ 1.12 (s, 9H), 4.31 (d, J=6.8 Hz, 2H), 7.63-7.71 (m, 2H), 8.05-8.07 (m, 1H), 8.16 (m, 1H), 8.55 (d, J=13.2 Hz, 1H), 9.29 (s, 1H), 12.85 (s, 1H); MS (m/z): 472.41 (M÷H)+.
