Procedure

A degassed solution of 3.8 g (0.012 mole) of methyl cis-3-azido-1-(2,4-dimethoxybenzyl)-4-oxoazetidine-2-carboxylate was treated with potassium persulfate and sodium monohydrogen phosphate as described in Preparation 2 to give methyl cis-3-azido-4-oxoazetidine-2-carboxylate which was purified by chromatography on silica gel with benzene-ethyl acetate as eluant.
