실험 절차

174.2 g of morpholine (1 mole), 69 g of potassium carbonate (0.5 mole) and 300 mL of acetone were heated to reflux. To the above solution 124.5 g (0.5 mole) of dodecylbromide were added dropwise. After the addition was complete, the reaction mixture was heated at reflux for four hours. The reaction mixture was filtered, and the solvent evaporated in vacuo to leave an oil, which was distilled under vacuum to give a colorless liquid. Yield is 112.9 g (90% of the theory). Proton NMR δ0.8 (S,3Hz), 1.2 (M, 22Hz), 2.3 (M,4Hz) and 3.5 (M,4Hz). Elemental analysis, observed (theory) is carbon 74.96 (75.25), hydrogen 13.21 (13.02), and nitrogen 5.38 (5.48). Close proximity between the observed and theoretical values indicates the positive identification of this compound. Similarly prepared compounds are shown in Table I:
