Procedure
307 mg of 4-[[(aminooxy)methyl]sulphonyl]pyrocatechol were reacted with 575 mg of (6R,7R)-7-(2-amino-4-thiazoleglyoxylamido)-3-[[(3-carboxy-7-methylpyrazolo[1,5-a]pyrimidin-5-yl)thio]methyl]-8-oxo-5-thia-1-azabicyclo[4.2.0]oct-2-ene-2-carboxylic acid in an analogous manner to the procedure described in Examples 11 or 7. There was obtained (6R,7R)-7-[(Z)-2-(2-amino-4-thiazolyl)-2-[[[(3,4-dihydroxyphenyl)sulphonyl]methoxy]imino]acetamido]-3-[[(3-carboxy-7-methylpyrazolo[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 white powder.
