Reaktionsschritte

A 1000 mL, round-bottomed flask equipped with air condensers and a magnetic stirring plate was charged with N,N-dimethyloctadecylamine (301.0 grams, 1.01 moles), 1-bromo-3-chloropropane (170.0 grams, 1.08 moles) and methanol (200 mL). The reaction was maintained at 65° C. for 18 hours. Solvent was removed by rotary evaporation under reduced pressure to yield clear oil. The oil was transferred to a beaker containing methylethylketone (250 mL) causing a white precipitate to form. Solid material was collected by vacuum filtration, resuspended in methylethylketone (250 mL), and collected by vacuum filtration an additional two times. The solid was placed in a vacuum oven at 30° C. overnight. Yield 274.9 grams (0.59 moles, 58%).
