Reaction Steps

By employing 0.805 g of (3R,4S)-4-acetylthio-3-tritylamino-2-oxoazetidine, 0.437 g of p-toluenesulfonic acid monohydrate, 0.19 g of pyridine, and, 0.175 g of DMF, 0.144 ml of diphosgene, 0.61 g of 2-(2-chloroacetamidothiazol-4-yl)-2-methoxyiminoacetic acid, 0.243 g of triethylamine and 2 ml of propylene oxide, a procedure similar to Reference Example 38B is taken to give 0.548 g of (3R,4S)-4-acetylthio-3-[2-(2-chloroacetoamidothiazole-4-yl)-2-methoxyiminoacetoamido]-2-oxoazetidine.
