(6R,7R)-7-(2-Amino-4-thiazoleglyoxylamido)-3-[[(3-carbamoyl-7-(trifluoromethyl)pyrazolo[1,5-a]pyrimidin-5-yl)-thio]methyl]-8-oxo-5-thia-1-azabicyclo[4.2.0]oct-2-ene-2-carboxylic acid was reacted with 4-[[(aminoxy)methyl]-sulphonyl]pyrocatechol according to the procedure described in Example 7. After purification of the product with the chromatographic procedure in Example 7 and lyophilization of the product, there was obtained (6R,7R)-7-[(Z)-2-(2-amino-4-thiazolyl)-2-[[[(3,4-dihydroxyphenyl)-sulphonyl]methoxy]imino]acetamido]-3-[[(3-carbamoyl-7-(tri-fluoromethyl)pyrazolo[1,5-a]pyrimidin-5-yl)thio]methyl]-8-oxo-5-thia-1-azabicyclo[4.2.0]oct-2-ene-2-carboxylic acid as a pale yellow powder.
