実験手順

To a solution of 0.101 g of the above sodium (3S,4S)-4-acetoxy-3-[2-(2-chloroacetamidothiazol-4-yl)-2-methoxyiminoacetamido]-2-oxoazetidine-1-sulfonate (syn-isomer) in 4 ml of water is added 28.4 mg of sodium monomethyldithiocarbamate under ice-cooling with stirring, and the mixture is stirred at room temperature for one hour. The insolubles are filtered off and the filtrate is purified on a column of XAD-II. The above procedure gives 55.4 mg of sodium (3S,4S)-4-acetoxy-3-[2-(2-aminothiazol-4-yl)-2-methoxyiminoacetamido]-2-oxoazetidine-1-sulfonate (syn-isomer).
