Versuchsvorschrift

(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 (60 mg) (0.101 mmol) and 40 mg (0.1318 mmol) of 1-[2-(aminooxy)-2-methylpropionyl]-2-(3,4-dihydroxybenzoyl)hydrazine hydrochloride are dissolved in 3 ml of absolute dimethylacetamide. After stirring at room temperature for 24 hours the solvent is removed at room temperature in a high vacuum. The residual oil is treated with water and the precipitated product is filtered off. The whole is washed in succession with water, ethanol and diethyl ether and dried at room temperature in a high vacuum. There are obtained 62 mg of (6R,7R)-7-[(Z)-2-(2-amino-4-thiazolyl)-2-[[1-[3-(3,4-dihydroxybenzoyl)carbazoyl]-1-methylethoxy]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.
