1-methylcycloheptan-1-amine

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A solution of 1,3-propanesultone (4.3 g, 35 mmol) in toluene (10 mL) was added dropwise to a the crude solution of 1-methyl-1-cycloheptylamine in MTBK (total volume 30 mL). The mixture was heated to reflux for 18 hours then was cooled to room temperature. The solid was collected by suction filtration, rinsed with acetone (2×5 mL). The solid was dried overnight at 45° C. in the vacuum oven. The title compound was obtained as a fine white solid (7.77 g, 31.2 mmol, 80% overall yield). 1H NMR (500 MHz, D2O) δ 1.27 (s, 3H), 1.40-1.60 (m, 8H), 1.71-1.81 (m, 4H), 2.00-2.06 (m, 2H), 2.95 (t, J=6.3 Hz, 2H), 3.13 (t, J=7.1 Hz, 2H); 13C NMR (125 MHz, D2O) δ 22.0, 22.1, 23.3, 29.5, 37.1, 40.0, 48.3, 64.0; ES-MS 250(M+H) The mixture was heated to reflux for 18 hours The solid was collected by suction filtration rinsed with acetone (2×5 mL) The solid was dried overnight at 45° C. in the vacuum oven
