반응 단계

Isopropylamine (2.5 mL, 29 mmol) was added to a solution of 1,3-propane sultone (3.05 g, 25 mmol) in a mixture of dichloromethane/ether (40 mL, 1:1). The mixture was heated at reflux for 3 hours. The reaction mixture was cooled to room temperature and hexane (10 mL) was added. The solid material was collected by filtration, rinsed with ether (10 mL), and dried in vacuo. Compound CG was obtained as a fine white powder (2.98 g, 65.6% yield). m.p. 240-43° C. 1H NMR (500 MHz, D2O) δ 1.06 (d, J=6.3 Hz, 6H), 1.86 (qt, J=7.6 Hz, 2H), 2.76 (t, J=7.6 Hz, 2H), 3.14 (t, J=7.8 Hz, 2H), 3.13-3.21 (m, J=6.6 Hz, 1H). 13C NMR (125 MHz, D2O) δ 18.2, 21.5, 25.8, 43.4, 47.9, 50.8.
