실험 절차

1,3-Diaminopropane (35.5 g, 0.48 mol) was dissolved in 300 mL CHCl3, and the solution was cooled to 0° C. A solution of N-(benzyloxycarbonyloxy)succinimide (4.5 g, 0.018 mol) in 150 mL CHCl3 was added dropwise over 6 h, with the internal temperature maintained below 10° C. After addition was complete, the reaction solution was stirred at room temperature overnight. The solution was washed with water, dried (Na2SO4), filtered and concentrated in vacuo to provide 3.0 g (80%) of the title compound as a low melting solid: 1H NMR (CDCl3) δ 1.25 (bs, 2 H), 1.63 (quintet, 2 H), 2.77 (t, 2 H), 3.2-3.34 (bm, 2 H), 5.09 (s, 2 H), 5.37 (bm, 1 H), 7.28-7.40 (m, 5 H); MS, m/e 209 ((M+H)+).
