Sodium Chloride → N-methyl-N-((1-phenyl-1H-1,2,3-triazol-4-yl)methyl)-5,6,7,8-tetrahydroquinolin-8-amine

To a solution of 1-phenyl-1H-1,2,3-triazole-4-carbaldehyde, 9, (0.23 g, 1.35 mmol) in 1,2-dichloroethane (2 mL) was added N-methyl-5,6,7,8-tetrahydroquinolin-8-amine, 5, (0.20 g, 1.23 mmol), sodium triacetoxyborohydride (0.10 g, 1.60 mmol), and 3 drops of acetic acid. The reaction mixture was stirred for 16 h at room temperature. The reaction mixture was then poured into aqueous saturated NaCl (10 mL) and was extracted with ethyl acetate (10 mL). The organic phase was dried over MgSO4, filtered, and concentrated in vacuo. The crude material was purified by silica gel chromatography (0-5% methanol/dichloromethane) yielding 35 mg (9%) of Y: 1H NMR (400 MHz, CDCl3) δ 8.74 (s, 1H), 8.47 (s, 1H), 7.78, (d, J=8.4 Hz, 2H), 7.50-7.39, (m, 4H), 7.20, (m, 1H), 4.72, (d, J=13.6 Hz, 1H), 4.63-4.58 (m, 2H), 2.90-2.60 (m, 6H), 2.22-2.17 (m, 1H), 2.10-1.95, (m, 1H), 1.90-1.78, (m, 1H).
