PROCEDURE
实验过程
(6R,7R)-7-(2-Amino-4-thiazoleglyoxylamido)-3-[[[2-(3,4-dihydroxyphenyl)-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 (1.3 g) and 0.79 g of 1-[2-(aminooxy)-2-methylpropionyl]-2-(3,4-dihydroxybenzoyl)hydrazine hydrochloride are dissolved in 10 ml of dimethylacetamide. After standing overnight the mixture is evaporated in a vacuum. The residue is digested with 25 ml of water and the precipitate formed is filtered off under suction and dried. There are obtained 1.7 g of (6R,7R)-7-[(Z)-2-(2-amino-4-thiazolyl)-2-[[1-[3-(3,4-dihydroxybenzoyl)carbazoyl]-1-methylethoxy]imino]acetamido]-3-[[[2-(3,4-dihydroxyphenyl)-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 colourless powder.
