The processes used for the barbiturate Peaceful Pill synthesis have been known for many years. Barbiturates are derivatives of barbituric acid. which was first synthesised by Adolph von Bayer in 1864, by condensing malonic acid with urea.
An easier method makes use of the di-ethyl ester of malonic acid (di-ethyl malonate) which reacts with urea in the presence of a catalyst sodium ethoxide; a base is formed by dissolving metallic sodium in absolute alcohol (ethanol).
