Versuchsvorschrift
7.7 g (35.6 mmol) of ethyl 3-ethylaminomethyl-3hydroxypyrrolidine-1-carboxylate are heated under reflux overnight with 22 g of Ba(OH)2. 8H2O in 220 ml of water. The mixture is filtered off with suction from BaCO3 and concentrated. The residue is boiled five times using 100 m of dioxane each time, and the dioxane solution is concentrated and distilled.
