Procedure

The title compound was prepared by following the procedure as described in Example-108 by using 3-(5-(aminomethyl)-2-(difluoromethyl)pyridin-3-yl)-1-(4-(trifluoromethyl)phenyl)-1H-1,2,4-triazol-5(4H)-one (step-1 of Example-186, 0.75 g, 0.19 mmol), cyclobutane carbonyl chloride (0.035 g, 0.29 mmol), TEA (0.059 g, 0.58 mmol) and DCM (10 mL) to afford 0.020 g of the desired product. 1H NMR (300 MHz, DMSO d6): δ 1.89-2.29 (m, 7H), 4.45 (s, 2H), 7.31-7.52 (m, 1H), 7.72 (d, J=8.4 Hz, 2H), 8.05 (s, 1H), 8.18 (d, J=8.4 Hz, 2H), 8.66 (s, 1H); MS (m/z): 468.26 (M+H)+.
