Isobutyraldehyde → 3-ethyl-2-(propan-2-yl)-1,3-oxazolidine

Participants

Reaction Steps

Iso-butyraldehyde (11.1 g; 0.15 moles) was added slowly over a period of 1 hour to N-ethyl-2-hydroxyethylamine (13.3 g; 0.15 moles) at a temperature of 25°-30° C. Benzene (100 ml) was then added, and the resulting solution was heated to reflux. Continuous azeotropic distillation removed 2.8 ml of water. The benzene was then removed by vacuum distillation to give the desired 2-isopropyl-3-ethyl-1,3-oxazolidine as a yellow liquid.
