The title compound was prepared by following the procedure as described for Example-31 by using methyl 4-(3-(2,6-dichlorophenyl)-4-ethyl-5-oxo-4,5-dihydro-1H-1,2,4-triazol-1-yl)-2-methoxybenzoate (Intermediate-41, 0.040 g, 0.09 mmol), 3-(trifluoromethyl)aniline (0.010 g, 0.6 mmol), trimethyl aluminium (2M solution in toluene) (1 mL) and dry toluene (5.0 mL) to afford 0.015 g of crude product which was purified by column chromatography in basic alumina eluting with 0.2% methanol:DCM to afford 0.015 g of pure product. 1H NMR (300 MHz, DMSO d6): δ 1.14 (t, 3H), 3.55-3.57 (m, 2H), 3.95 (s, 3H), 7.46 (m, 1H), 7.59 (t, 1H), 7.69-7.81 (m, 6H), 7.94 (m, 1H), 8.25 (s, 1H), 10.38 (s, 1H); MS (m/z): 551.11 (M+H)+.
