Versuchsvorschrift

In water (4 ml) was dissolved 7β-(2-thienylacetamido)-3-mandelyloxymethyl-3-cephem-4-carboxylic acid (0.49 g) together with 5-mercapto-1-methyl-1H-tetrazole (0.12 g) and sodium hydrogen carbonate (0.17 g). The solution was stirred at 60° C. for 30 minutes. After the reaction had been completed, the reaction mixture was treated by a procedure similar to that described in Example 85. The procedure provided 7β-(2-thienylacetamido)-3-(1-methyl-1H-tetrazol-5-yl)thiomethyl-3-cephem-4-carboxylic acid (0.40 g).
