Participants

Reaction Steps

The title compound was prepared by following the procedure as described for step-2 of Intermediate-30 by using methyl 4-(3-(5-(aminomethyl)-2-chlorophenyl)-5-oxo-4,5-dihydro-1H-1,2,4-triazol-1-yl)benzoate hydrochloride (0.250 g, 0.5 mmol), cyclopropane carbonyl chloride (0.108 g, 1.0 mmol), DIPEA (2.0 mL), THF (10 mL) to afford 0.200 g of desired product. 1H NMR (300 MHz, DMSO d6): δ 1.05 (s, 2H), 1.60 (m, 2H), 3.14 (m, 1H), 3.87 (s, 3H), 4.33 (d, J=5.7 Hz, 2H), 7.41-7.61 (m, 4H), 8.11-8.17 (m, 3H), 8.69 (m, 1H), 12.65 (br s, 1H); MS (m/z): 427.14 (M+H)+.
