Procedure

The title compound was prepared by following the procedure as described for step-6 of Intermediate-26 by using methyl 4-(3-(2-chloro-6-iodophenyl)-5-oxo-4,5-dihydro-1H-1,2,4-triazol-1-yl)-2-methoxybenzoate (step-1 of Intermediate-34, 0.100 g, 0.20 mmol), 4-fluoro-3-(trifluoromethyl)aniline (0.044 g, 0.34 mmol), trimethyl aluminium (2M solution in toluene) (1.0 mL) and dry toluene (8.0 mL) to afford 0.020 g of desired product. 1H NMR (300 MHz, DMSO d6): δ 3.94 (s, 3H), 3.78 (t, 1H), 7.52 (t, 2H), 7.71-7.82 (m, 3H), 8.03 (d, J=6.6 Hz, 2H), 10.38 (s, 1H), 12.69 (br s, 1H).
