실험 절차

To a solution of 5-(3-(aminomethyl)-2,6-dimethylphenyl)-2-(4-(trifluoromethyl)phenyl)-2H-1,2,4-triazol-3(4H)-one (Intermediate-66, 0.050 g, 0.138 mmol) in dry THF:DMF (4 mL:1 mL), TBTU (0.132 g, 0.414 mmol) and TEA (1.0 mL) were added and the reaction mass was stirred for 1 h under nitrogen atmosphere. To the reaction mass, (R)-(−)-tetrahydrofuran-2-carboxylic acid (0.024 g, 0.207 mmol) was added and stirred for 18 h at room temperature. After completion of the reaction, the reaction mass was quenched in water, extracted with ethyl acetate and concentrated to afford crude product which was purified by column chromatography by eluting with solution of 2% ammonia in 10% MeOH:DCM to afford 0.017 g of the title product. 1H NMR (400 MHz, DMSO d6): δ 1.79 (m, 3H), 1.87 (m, 3H), 2.20 (s, 6H), 3.74-3.79 (m, 1H), 3.88-3.92 (m, 1H), 4.25 (d, J=4.5 Hz, 2H), 7.16 (d, J=6.0 Hz, 1H), 7.25 (d, J=6.0 Hz, 1H), 7.82 (d, J=6.6 Hz, 1H), 8.17 (d, J=6.3 Hz, 2H), 8.24 (t, J=4.8 Hz, 2H), 12.30 (br s, 1H); MS (m/z): 461.14 (M+H)+.
