Versuchsvorschrift

9 g (45.4 mmol) of ethyl 2-methyl-2,7-diazabicyclo [3.3.0]octane-7-carboxylate are heated under reflux overnight with 50 ml of concentrated hydrochloric acid. The mixture is rendered alkaline with potassium carbonate, extracted ten times using 50 ml of chloroform each time, dried over potassium carbonate and concentrated, and the residue is distilled.
