Participants

Reaction Steps

1,2,3,4-Tetrahydroquinoylamine (0.925 g, 6.25 mmol) and 4-piperidone monohydrate hydrochloride (0.960 g, 6.25 mmol) were dissolved in EtOH (15 mL). Conc. HCl (0.52 mL, 6.25 mmol) was added. The reaction was refluxed for 3 hrs and then cooled to RT. The precipitate was collected by vacuum filtration. The residue was washed with 5 mL of EtOH, to afford the title compound (1.32 g, 85%) as a pure, white powder. 1H NMR (CD3OD, 300 MHz) δ 7.22 (d, 1H, J=8.1 Hz), 6.92–6.97 (m, 1H), 6.86 (d, 1H, J=7.2 Hz), 4.87 (s, 2H), 4.05 (t, 2H, J=6.0 Hz), 3.61 (t, 2H, J=6.0 Hz), 3.14 (t, 2H, J=6.0 Hz), 2.94 (t, 2H, J=6.3 Hz), 2.16–2.24 (m, 2H) ppm.
