9.3 g (40 mmol) of ethyl 5-chloro-2-methyl-2,7-diazabicyclo[3.3.0]octane-7-carboxylate are refluxed overnight together with 50 ml of concentrated hydrochloric acid. The mixture is concentrated, the concentrate is taken up in 30 ml of water, and this mixture is rendered alkaline using potassium carbonate and extracted five times using 50 ml portions of chloroform. The extracts are dried over potassium carbonate, concentrated and distilled.
