Sodium Iodide → N-methyl-N-(prop-2-ynyl)-5,6,7,8-tetrahydroquinolin-8-amine

Participants

Reaction Steps

To a solution of N-methyl-5,6,7,8-tetrahydroquinolin-8-amine, 5, (0.50 g, 3.08 mmol) in THF (15 mL) was added propargyl bromide (0.28 mL, 3.08 mmol), sodium iodide (0.05 g, 0.31 mmol) and sodium carbonate (0.98 g, 9.24 mmol). The reaction mixture was stirred at room temperature for 3 h. The mixture was diluted with water, extracted with ethyl acetate. The organic phase was dried (MgSO4), filtered and concentrated in vacuo. The crude solid was used without further purification: 1H NMR (d6-DMSO) δ 8.30 (d, J=4.4 Hz, 1H), 7.44 (d, J=8.0 Hz, 1H), 7.13 (dd, J=8.0, 5.2 Hz, 1H), 3.74 (dd, J=4.8, 4.8 Hz, 1H), 3.47 (ddd, J=16.8, 2.4, 2.4 Hz, 2H), 3.06 (s, 1H), 2.80-2.60 (m, 2H), 2.12 (s, 3H), 2.12-1.87 (m, 2H), 1.74-1.68 (m, 1H), 1.62-1.55 (m, 1H); ESI+ MS: m/z (rel intensity) 201.1 (100, [M+H]+).
