Procedure
A solution of 1.86 g of the hydrochloride of aminooxyacetic acid in 20 ml of water is treated under stirring at 0° with 3.16 g of the hydrochloride of 6-amino-1,4,5a,6-tetrahydro-3-hydroxy-1,7-dioxo-3H,7H-azeto[2,1-b]furo[3,4-d][1,3]thiazin. The mixture is stirred for ca. 8 hours at 0°. 7-Amino-3-[[(carboxymethoxy)imino]methyl]-3-cephem-4-carboxylic acid precipitates in form of colourless crystals, which are filtered off, washed with 5 ml of cold water and 5 ml of acetone and dried.
