실험 절차

1.24 g of the hydrogen carbonate of aminoguanidine are dissolved in 9.15 ml of 2 N HCl and added under stirring to a solution of 3.2 g of the trifluoroacetate of N-(1,4,5a,6-tetrahydro-3-hydroxy-1,7-dioxo-3H,7H-azeto[2,1-b]furo[3,4-d][1,3]-thiazin-6-yl)-2-(2-aminothiazol-4yl)-(Z)-2-methoxyimino acetic acid amide in 125 ml of 4% aqueous acetonitrile. After ca. 90 minutes the precipitated dihydrochloride of 7-[(2-Amino-4-thiazolyl)(methoxyimino)acetyl]amino-3-[[(aminoimino-methyl)-hydrazono]methyl]-3-cephem-4-carboxylic acid is filtered off, washed with acetonitrile and dried.
