Procedure

A solution containing 230 mg (1.45 mmole) of cis-3-azido-4-oxo-2-azetidineacetaldehyde, 20 mg of p-toluenesulfonic acid and 0.5 ml of benzylthiol in 25 ml of benzene and 5 ml of dimethylformamide was heated under reflux for 1 hour. After cooling, the mixture was shaken with ethyl acetate and 5% sodium bicarbonate, the organic phase washed with brine, dried and evaporated to dryness. Chromatography over silica gel with chloroform afforded 83 mg (13%) of the title compound.
