Procedure

A solution of 16.4 g (49.4 mmol, 88%) of ethyl 2-benzyl-5-fluoro-2,7-diazabicyclo[3.3.0)octane-7-carboxylate in 25 ml of absolute tetrahydrofuran is added dropwise to 4.3 g (0.11 mol) of lithium aluminium hydride in 125 ml of absolute tetrahydrofuran, and the mixture is subsequently refluxed overnight. The mixture is decomposed in succession with in each case 4.5 ml of water, 15% strength potassium hydroxide solution and water, and the inorganic salts are filtered off with suction and extracted three times by boiling with 50 ml portions of tetrahydrofuran. The organic solutions are concentrated, and the residue is distilled.
