PROCEDURE

实验过程

In 3 ml of water is dissolved 0.204 g of the above sodium 3-[2-[2-(2-chloroacetamido-4-thiazolyl)-2-methoxyiminoacetamido]-2-(2-chloroacetamido-4-thiazolyl)acetamido]-2-oxoazetidine-1-sulfonate (syn-isomer) and while the solution is stirred under ice-cooling, 0.085 g of sodium N-methyldithiocarbamate is added. The mixture is stirred for an hour, after which the insoluble matter is filtered off. The filtrate is purified by Amberlite, XAD-II chromatography to provide 0.1 g of sodium 3-[2-[2-(2-amino-4-thiazolyl)-2-methoxyiminoacetamido]-2-(2-amino-4-thiazolyl)acetamido]-2-oxoazetidine-1-sulfonate (syn-isomer).
