Versuchsvorschrift

A solution of iodododecane (18.1 g, 61.09 mmol) and 2-(methylamino)ethanol (23.0 g, 0.3 mol) in isopropanol (75 ml) was heated under reflux for 3 h. The cooled mixture was diluted with ether (500 ml), washed with water, brine and dried (magnesium sulfate). Evaporation of the solvent under reduced pressure and distillation of the residue under vacuum gave 14.5 g (97%) of N-methyl-N-dodecylethanolamine as a clear oil: b.p. 100-111° C./0.3 torr (bulb to bulb distillation, air bath temperature).
