Participants

Reaction Steps

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]benzoate (step-2 of Intermediate-9, 0.100 g, 0.28 mmol), 4-chloro-N′-hydroxybenzimidamide (Intermediate-19, 0.073 g, 0.43 mmol), sodium hydride (0.018 g, 0.43 mmol) and dry THF (5.0 mL) to afford 0.025 g of desired product. 1H NMR (DMSO-d6): δ 7.51 (t, J=8.7 Hz, 1H), 7.59 (d, J=8.4 Hz, 1H), 7.67-7.73 (m, 3H), 8.11 (d, J=8.1 Hz, 2H), 8.24-8.29 (m, 4H), 12.85 (br s, 1H); MS (m/z): 467.87 [M+H]+.
