Procedure

To a solution of p-nitrobenzyl α-[4-cyclopropylmethoxycarbonylthio-3-phenoxyacetamido-2-oxoazetidin-1-yl]-α-(1-methanesulfonyloxyethylidene)acetate (1.12 g) in benzene (11 ml) is added morpholine (0.26 ml) under ice cooling, and the mixture is kept at 10° C. overnight. The reaction mixture is washed with water, dried, and evaporated under reduced pressure. Purification of the obtained residue (1 g) by chromatography over silica gel (10 g) using a mixture of benzene and ethyl acetate (1:2) gives p-nitrobenzyl α-[4-cyclopropylmethoxycarbonylthio-3-phenoxyacetamido-2-oxoazetidin-1-yl]-α-(1-morpholinoethylidene)acetate
