Versuchsvorschrift

A one-liter, 3-necked, round-bottomed flask equipped with air condensers and a magnetic stirring plate was charged with N,N-dimethyltetradecylamine (311.59 grams, 1.29 moles), 1-bromo-3-chloropropane (203.09 grams, 1.29 moles) and methanol (250 mL). Reaction was maintained at 65° C. for 24 hours. Methanol was removed by rotary evaporation under reduced pressure to yield a sludge. To the sludge was added methyl-tert-butylether (500 mL) causing a white solid to slowly form The mixture was stirred for one-half hour and white, paste-like particulate was collected by vacuum filtration. The solid was placed in a vacuum oven at 35° C. for 24 hours. Yield 420 grams (1.05 molest 82%).
