실험 절차

To a solution of N-methyl-5,6,7,8-tetrahydroquinolin-8-amine, 5, (0.39 g, 2.40 mmol) in 1,2-dichloroethane (4 mL) was added 4-methyl-5-phenyl-4H-1,2,4-triazole-3-carbaldehyde, 36, (0.41 g, 2.20 mmol), sodium triacetoxyborohydride (0.84 g, 3.90 mmol), and AcOH (1 drop). The reaction mixture was heated to 65° C. and stirred for 18 h. The reaction mixture was cooled to room temperature, poured into saturated aqueous NaHCO3 (10 mL) and extracted with ethyl acetate (2×10 mL). The combined organic phases were washed with brine then dried over MgSO4, filtered, and concentrated in vacuo. The crude material was purified via chromatography on basic alumina (0-5% methanol/dichloromethane) yielding BP: 1H NMR (400 MHz, CDCl3) δ 8.39, (d, J=4.8 Hz, 1H), 7.58-7.53 (m, 2H), 7.46-7.39, (m, 3H), 7.32, (d, J=8.4 Hz, 1H), 7.01, (dd, J=7.2, 4.4 Hz, 1H), 4.04-3.92, (m, 2H), 3.78, (d, J=14.0 Hz, 1H), 2.85-2.74, (m, 1H), 2.71-2.62 (m, 1H), 3.33, (s, 3H), 2.12-1.94 (m, 3H), 1.74-1.62 (m, 1H); ESI+ MS: m/z (rel intensity) 334 (100, M+H).
