Versuchsvorschrift

To a solution of 1-(benzyloxycarbonyl)azetidine-3-carboxylic acid (21.25 mmol, 5 g) in dichloromethane (60 ml) under a nitrogen atmosphere were added N,N-dimethylformamide (1.063 mmol, 0.083 ml) and oxalyl chloride (2M solution in dichloromethane, 25.00 mmol, 12.5 ml). After stirring at room temperature for two hours the reaction mixture was concentrated in vacuo to give 5.53 gram of crude benzyl 3-(chlorocarbonyl)azetidine-1-carboxylate.
