実験手順
To a solution of 0.250 g sodium (3S,4S)-4-acetoxy-3-[2-(2-chloroacetamidothiazol-4-yl)-2-isopropoxyiminoacetamido]-2-oxoazetidine-1-sulfonate in 4 ml of water is added 73 mg of sodium monomethyldithiocarbamate under ice-cooling 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 0.153 g of sodium (3S,4S)-4-acetoxy-3-[2-(2-aminothiazol-4-yl)-2-isopropoxyiminoacetamido]-2-oxoazetidine-1-sulfonate.
