Procedure
A degassed solution of cis-3-azido-4-oxo-2-azetidinylmethyl tosylate (0.41 g, 1.4 mmol) in dimethylformamide (5 ml) was heated to 90° with LiBr (0.43 g, 5 mmol) for 4 hours. The reaction was poured into ethyl acetate and washed copiously with water. The dried solution was evaporated to give the title compound.
