実験手順

A 268 mg quantity of 3,4,5-trimethoxy-2,6-dichlorobenzyl 2-[3-phenoxyacetamido-4-(4-methylbenzothiazol-2-yldithio)-2-azetidinon-1-yl]-3-methyl-3-butenoate and 69 mg of benzenesulfonyl cyanide were dissolved in 3 ml of acetone. To the solution was added 3 mg of sodium benzenesulfinate and the mixture was reacted at room temperature for 2 hours. The same subsequent procedure as in Example 5 was followed, producing 3,4,5-trimethoxy-2,6 dichlorobenzyl 2-(3-phenoxyacetamido-4-benzenesulfonylthio-2-azetidinon-1-yl)-3-methyl-3-butenoate in a yield of 85%. The NMR spectrum data of the compound thus obtained were identical with those of the desired compound. The NMR spectrum data are shown below in Table 2.
