Versuchsvorschrift

7-[2-(2-Aminothiazol-4-yl)-2-methoxyiminoacetamido]-3-cephem-4-carboxylic acid (syn isomer, 1.15 g.) was added to a suspension of magnesium hydroxide (0.088 g.) in water (100 ml.), and the mixture was stirred at 70° C. for 30 minutes to give a solution. After the resultant solution was filtered, the filtrate was lyophilized to give magnesium 7-[2-(2-aminothiazol-4-yl)-2-methoxyiminoacetamido]-3-cephem-4-carboxylate (syn isomer, 1.1 g.).
