実験手順

(6R,7R)-7-(2-Amino-4-thiazoleglyoxylamido)-3-[[[5-(hydroxycarbamoyl)-2-methyl-s-triazolo[1,5-a]pyrimidin-7-yl]thio]methyl]-8-oxo-5-thia-1-azabicyclo[4.2.0]oct-2-ene-2-carboxylic acid (65 mg) (0.11 mmol) and 37 mg (0.14 mmol) of 4-[[(aminooxy)methyl]sulphonyl]pyrocatechol hydrochloride are dissolved in 3 ml of absolute dimethylacetamide. After stirring at room temperature for 24 hours a further 4.2 mg (0.016 mmol) of 4-[[(aminooxy)methyl]sulphonyl]pyrocatechol hydrochloride are added. After a further 24 hours the solvent is removed in a high vacuum at room temperature and the residue is treated with water. The precipitated product is filtered off and washed in succession with water and diethyl ether. After drying in a high vacuum there are obtained 55 mg of (6R,7R)-7-[(Z)-2-amino-4-thiazolyl)-2-[[[(3,4-dihydroxyphenyl)sulphonyl]methoxy]imino]acetamido]-3-[[[5-(hydroxycarbamoyl)-2-methyl-s-triazolo[1,5 -a]pyrimidin-7-yl]thio]methyl]-8-oxo-5-thia-1-azabicyclo[4.2.0]oct-2-ene-2-carboxylic acid as a beige powder.
