Propane sultone → HCID 11358219, compound

Participants

Reaction Steps

To a solution of 3,4-dimethoxybenzylamine (2.2 mL, 15.0 mmol) in acetone (20 mL) was added 1,3-propane sultone (1.97 g, 15.8 mmol). The mixture was stirred at reflux for 2 hours. The reaction mixture was cooled to room temperature. The solid material was collected by filtration, washed with acetone (2×25 mL) and dried in vacuo. The crude product was suspended in 90% acetone/MeOH (75 mL). The suspension was stirred at reflux for 30 sec., the solid material was collected by filtration, and dried in vacuo. Compound S (1.84 g, 43%) was isolated as a white solid. 1H NMR (D2O, 500 MHz) 8 ppm 6.96 (m, 3H), 4.06 (s, 2H), 3.74 (s, 6H), 3.07 (t, 1H, J=7.8 Hz), 2.86 (t, 1H, J=7.8 Hz), 2.01 (m, 2H). 13C NMR (D2O, 125 MHz) 8 ppm 149.23, 148.50, 123.63, 123.37, 55.90, 55.86, 50.96, 48.06, 45.62, 21.39. ES-MS 290 (M+1).
