Diisopropylethylamine → N-(4-Chloro-3-(1-(4-(trifluoromethyl)phenyl)-4,5-dihydro-5-oxo-1H-1,2,4-triazol-3-yl)benzyl)-1-methyl-1H-imidazole-2-carboxamide

Participants

Reaction Steps

The title compound was prepared according to the procedure described in Example-108 by using 3-(5-(aminomethyl)-2-chlorophenyl)-1-(4-(trifluoromethyl)phenyl)-1H-1,2,4-triazol-5(4H)-one (Intermediate-63, 0.070 g, 0.189 mmol), 1-methyl-1H-imidazole-2-carbonyl chloride (0.026 g, 0.283 mmol), dry THF (5 mL), DIPEA (2 mL). The obtained crude was purified by column chromatography using 2% ammonia in 20% MeOH:DCM as mobile phase to afford 0.020 g of the desired title product. 1H NMR (300 MHz, DMSO d6): δ 3.50 (s, 3H), 4.41 (d, J=18.0 Hz, 1H), 6.99 (s, 1H), 7.43 (br, 2H), 7.67 (d, 1H), 7.78 (s, 1H), 8.28 (d, J=4.5 Hz, 2H), 8.30 (s, 1H), 9.08 (t, 1H); MS (m/z): 477.10 (M+H)+.
