Versuchsvorschrift

0.228 g (0.4 mmol) of (6R,7R)-7-(2-amino-4-thiazoleglyoxylamido)-3-[[(2-carbamoyl -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 was dissolved in 2 ml of dimethylacetamide. 0.140 g (0.52 mmol) of 1-[2-(aminooxy)-2-methylpropionyl]-2-[(1,4-dihydro-5-hydroxy-4-oxo-2-pyridyl) carbonyl]hydrazine and 0.100 g (0.52 mmol) of p-toluenesulfonic acid hydrate were added. After stirring for 20 hours at room temperature the dimethylacetamide was evaporated off at strongly reduced pressure and the residue was taken up in water and stirred for 15 minutes in order to completely precipitate the product. The product was filtered off, washed well with water and dried under strongly reduced pressure at room temperature. (6R,7R)-7-[(Z)-2-(2-amino-4-thiazolyl)-2-[[1,4-dihydro-5-hydroxy -4-oxo-2-pyridyl)carbonyl]carbazoyl]-1-methylethoxy]imino] -acetamido]-3-[[[2-carbamoyl-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 was obtained as beige-colored powder.
