3-Azaspiro[5,5]undecane (0.38 g, 2 mmol) and 2-methylthio-2-imidazoline hydroiodide (0.44 g, 1.8 mmol) was refluxing in CH3OH overnight, concentrated in vacuo and purified by flash chromatography to give yellow oil (0.26 g, 65% yield). 1H NMR (360 MHz, CDCl3) δ 8.27 (br s, 2H), 3.72 (s, 4H), 3.39 (t, J=5.83 Hz, 4H), 1.50 (t, J=5.94 Hz, 4H), 1.47-1.44 (m, 10H); 13C NMR (90 MHz, CDCl3) δ 159.48, 43.39, 42.73, 36.02, 35.26, 30.83, 26.65, 21.61. 21.49; ESI-MS: Calculated for C13H24IN3 (M−I)+ 222.3, Found: 222.5.
