Reaction Steps

(±)-3-[(Azidophenylacetyl)amino]-3-methoxy-2-oxo-1-azetidinesulfonic acid, potassium salt (209 mg; see Example 88) is dissolved in 60 ml of dry methanol. Anhydrous trifluoroacetic acid (0.6 ml) and 10% palladium on carbon (105 mg) are added and the mixture is hydrogenated for 1 hour. The catalyst is removed by filtration and the filtrate is evaporated in vacuo to yield 271 mg of crude product.
