Reaction Steps

The title compound was prepared according to the procedure described in Example-108 by using 5-(5-(aminomethyl)-2-chlorophenyl)-2-(4-chloro-3-methylphenyl)-2H-1,2,4-triazol-3(4H)-one (Intermediate-106, 0.300 g, 0.859 mmol), pivaloyl chloride (0.130 g, 1.03 mmol), TEA (2.0 mL), dry THF (5 mL) to afford 0.140 g of the desired product. 1H NMR (300 MHz, DMSO 4): δ 1.13 (s, 9H), 2.37 (s, 3H), 4.29 (d, J=5.7 Hz, 2H), 7.41 (d, J=8.7 Hz, 1H), 7.51 (d, J=8.7 Hz, 1H), 7.58 (s, 2H), 7.70 (br d, 1H), 7.91 (s, 1H), 8.20 (d, J=6.0 Hz, 1H), 12.56 (s, 1H); MS (m/z): 433.38 (M+H)+.
