실험 절차

The title compound was prepared according to the procedure described in Example-107 by using 3-(5-(aminomethyl)-2-chlorophenyl)-1-(4-(trifluoromethyl)phenyl)-1H-1,2,4-triazol-5(4H)-one (Intermediate-63, 0.070 g, 0.189 mmol), THF:DMF (5 mL:1 mL), (S)-(−)tetrahydrofuran-2-carboxylic acid (0.032 g, 0.283 mmol), TBTU (0.182 g, 0.567 mmol), and TEA (3.0 mL). The obtained crude was purified by column chromatography on basic alumina by eluting solution of 2% ammonia in 10.0% MeOH:DCM to afford 0.010 g of the desired product. 1H NMR (300 MHz, DMSO d6): δ 1.80 (m, 3H), 2.15 (m, 1H), 3.75 (m, 1H), 3.94 (m, 1H), 4.27-4.32 (m, 3H), 7.42 (d, 1H), 7.60 (d, 2H), 7.85 (d, J=5.4 Hz, 2H), 8.20 (d, J=4.5 Hz, 2H), 8.52 (s, 1H), 12.50 (s, 1H); MS (m/z): 467.08 (M+H)+.
