Procedure

7.6 g (31.6 mmol) of ethyl 2-phenyl-2,7-diazabicyclo[3.3.0]octane-7-carboxylate together with 50 ml of concentrated hydrochloric acid are refluxed overnight. The mixture is concentrated, the residue is taken up in 50 ml of 10% strength sodium hydroxide solution, and this mixture is extracted five times using 50 ml portions of chloroform. The extracts are dried over potassium carbonate and concentrated, and the residue is distilled.
