Procedure

(6R,7R)-7-(2-Amino-4-thiazoleglyoxylamido)-3-[[[2-(N-hydroxy-N-methylcarbamoyl)-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 (40 mg) (0.066 mmol) and 29 mg (0.086 mmol) of 1-[2-(aminooxy)-2-methylpropionyl]-2-(3,4-dihydroxybenzoyl)hydrazine hydrochloride are dissolved in 1 ml of absolute dimethylacetamide. After stirring for 20 hours the solution is concentrated at room temperature in a high vacuum. The residue is crystallized from ethanol. There are obtained 16 mg of (6R,7R)-7-[(Z)-2-(2-amino-4-thiazolyl)-2-[[1-[3-(3,4-dihydroxybenzoyl)carbazoyl]-1-methylethoxy]imino]acetamido]-3-[[[2-(N-hydroxy-N-methylcarbamoyl)-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 brown powder.
