실험 절차
A mixture of morpholine (261 ml, 3.00 mol) and 1-bromo-3-chloropropene (148 ml, 1.50 mol) in toluene (900 ml) was stirred for 18 hours at ambient temperature. Additional 1-bromo-3-chloropropane (25 ml, 0.25 mol) was added, the reaction was stirred for a further 1 hour and then filtered to remove the precipitated solid before the filtrate was concentrated in vacuo. Distillation of the crude oil yielded N-(3-chloropropyl)-morpholine (119.3 g, 49% yield) as the fraction boiling at 70-80° C./2.6 mmHg:
