Versuchsvorschrift
Formaldehyde (60 ml of 40% solution) was added to a stirred solution of potassium ethyl malonate (34g) and dimethylamine (40 ml of 26% solution) in water (100 ml) at 15° C. The solution was stirred at laboratory temperature for one hour and then boiled under reflux for one hour. After cooling the solution was extracted with ether and the ether was evaporated to leave the product as a yellow oil. This was distilled to give a clear oil (boiling point 84° C/20 mm).
