Procedure

The title compound was prepared by following the procedure as described for Example-40 by using methyl 4-(3-(2-chloro-6-fluorophenyl)-5-oxo-4,5-dihydro-1H-1,2,4-triazol-1-yl)-2-methoxybenzoate (step-2 of Intermediate-15, 0.100 g, 0.26 mmol), 3-fluoro-N′-hydroxy-5-(trifluoromethyl)benzimidamide (Intermediate-22, 0.088 g, 0.39 mmol), sodium hydride (0.017 g, 0.42 mmol) and dry THF (5.0 mL) at RT to afford 0.010 g of desired product. 1H NMR (DMSO-d6): δ 4.01 (s, 3H), 7.50 (m, 1H), 7.60 (m, 1H), 7.70 (m, 1H), 7.84 (m, 1H), 7.92 (br s, 1H), 8.02 (d, 1H), 8.18 (m, 2H), 8.25 (d, 1H), 12.95 (br s, 1H); MS (m/z): 550.07 [M]+.
