Procedure

To a solution of methyl 4-(1-(2,6-dichlorophenyl)-5-oxo-4,5-dihydro-1H-1,2,4-triazol-3-yl)-2-methoxybenzoate (Intermediate-46, 0.070 g, 0.17 mmol) in dry toluene was added 3-(trifluoromethyl)aniline (0.043 g, 0.17 mmol) followed by addition of trimethyl aluminum (2M solution in toluene) (0.5 mL). The reaction mixture was refluxed for 1 hr under inert atmosphere. The reaction mixture was brought to RT and quenched with water. Few drops of dilute HCl were added and the reaction mixture was extracted with DCM and concentrated. The obtained product was purified with column chromatography to afford 0.050 g of desired product. 1H NMR (300 MHz, DMSO d6): δ 3.95 (s, 3H), 7.46 (d, J=6.9 Hz, 1H), 7.54-7.65 (m, 4H), 7.72-7.76 (m, 3H), 7.94 (d, J=8.4 Hz, 1H), 8.24 (s, 1H), 10.51 (s, 1H), 12.85 (s, 1H); MS (m/z): 523.04 (M+).
