실험 절차

(6R,7R)-7-(2-Amino-4-thiazoleglyoxylamido)-3-[[[2-(hydroxycarbamoyl)-5-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 (25 mg) (0.042 mmol), 8.6 mg (0.055 mmol) of 2-(aminooxy)methyl-5-hydroxy-4(1H)-pyrimidinone and 10.5 mg (0.055 mmol) of p-toluenesulphonic acid hydrate are dissolved in 3 ml of absolute dimethylacetamide. After stirring at room temperature for 24 hours the solvent is removed in a high vacuum at room temperature and the residue is treated with 3 ml of 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 20 mg of (6R,7R)-7-[(Z)-2-(2-amino-4-thiazolyl)-2-[[(1,4-dihydro-5-hydroxy-4-oxo-2-pyrimidinyl)methoxy]imino]acetamido]-3-[[[2-(hydroxycarbamoyl)-5-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.
