Procedure
Pyrrolidine (10 g, 0.14 mol), acetone (28 ml), 5M NaOH solution (21 ml) and 1-bromo-3-chloropropane (24.4 g, 0.15 mol) were stirred together under N2 for 8 hours. The organic layer was separated and concentrated in vacuo. The crude product was purified by vacuum distillation (b.p. 90° C./30 mbar) to give the title compound (11.7 g, 57%) as a colourless oil.
