Procedure: A solution of 1,3-propanesultone (5.00 g, 40 mmol) in toluene (10 mL) was added dropwise to a the crude solution of 1-methyl-1-cyclohexylamine in MTBK (total volume 30 mL). The mixture was heated to reflux for 18 hours then cooled to room temperature. The solid was collected by suction filtration, rinsed with acetone (2×8 mL). The solid was dried overnight at 45° C. in the vacuum oven. The title compound was obtained as a fine white solid (9.22 g). However, the proton NMR and the ES-MS were not clean. The solid was suspended in methanol (45 mL) and the suspension was warmed to reflux. Water (12 mL) was added dropwise until a clear yellow solution was obtained. The mixture was slowly cool to room temperature with stirring. The solid was collected by suction-filtration, rinsed with methanol (2×5 mL). Another crop was collected from the filtrate. Both crops were dried overnight at 45° C. in the vacuum oven. The title compound was obtained as a fine white solid (6.82 g, 29.0 mmol, 66% overall yield). Both crops were identical and were mixed for submitting the compound. 1H NMR (500 MHz, D2O) δ 1.04-1.11 (m, 1H), 1.19 (s, 3H), 1.31 (q, J=12.2 Hz, 2H), 1.40 (qt, J=12.2 Hz, 2H), 1.46-1.62 (m, 2H), 1.63 (br d, J=11.7 Hz, 2H), 1.94 (q, J=7.3 Hz, 2H), 2.86 (t, J=7.1 Hz, 2H), 3.03 (t, J=7.6 Hz, 2H); 13C NMR (125 MHz, D2O) δ 19.1, 21.5, 22.0, 24.6, 34.1, 39.1, 48.2, 60.2; ES-MS 236 (M+H).
