Procedure

(ci) 1.58 g (1.2 equivalents) of silver p-toluenesulphinate are added in portions, in the course of 10 minutes, to a solution of 3.25 g (5.0 mmols) of 2-[4-(benzthiazol-2-yldithio)-3-phenoxyacetamido-2-oxoazetidin-1-yl]-3-methylenebutyric acid p-nitrobenzyl ester in 200 ml of acetone/water, 9:1 (v/v). The suspension is stirred for one hour at room temperature, filtered and further processed as described in Example 1(c). 2-[4-(p]Toluenesulphonylthio)-3-phenoxyacetamido-2-oxoazetidin-1-yl]-3-methylenebutyric acid p-nitrobenzyl ester is obtained in quantitative yield.
