The title compound was prepared according to the procedure described in Example-107 by using 5-(5-(aminomethyl)-2-chloro-4-fluorophenyl)-2-(4-(trifluoromethyl)phen yl)-2H-1,2,4-triazol-3(4H)-one (Intermediate-70, 0.090 g, 0.233 mmol), THF:DMF (5 mL:1 mL), (R)-(−)-tetrahydrofuran-2-carboxylic acid (0.040 g, 0.349 mmol), TBTU (0.224 g, 0.699 mmol), and TEA (0.5 mL). The obtained crude was purified with column chromatography using basic alumina as stationary phase and 2% ammonia in 10.0% MeOH:DCM solution as mobile phase to afford 0.015 g of the desired product. 1H NMR (400 MHz, DMSO d6): δ 1.78-1.91 (m, 2H), 2.09-2.15 (m, 1H), 3.74 (m, 1H), 3.88-3.94 (m, 1H), 4.28 (m, 1H), 4.43 (m, 2H), 7.65 (m, 2H), 7.86 (d, J=8.72 Hz, 2H), 8.18 (d, J=8.52 Hz, 2H), 8.45 (d, J=16.0 Hz, 1H), 12.71 (s, 1H).
