Procedure
When 3-hydroxymethyl-7-methoxy-7-(2-thienylacetamido)-3-cephem-4-carboxylic acid is reacted with 2,2,2-trichloroethoxycarbonyl isocyanate and the resulting imidodicarboxylate is deblocked following the procedures described in Example 5, 3-carbamoyloxymethyl-7-methoxy-7-(2-thienylacetamido)-3-cephem-4-carboxylic acid is obtained.
