실험 절차
(S)-2-Oxo-3-[[(phenylmethoxy)carbonyl]amino]-1-azetidinesulfonic acid, tetrabutylammonium salt (2 g; see Example 4) is dissolved in 100 ml of dimethylformamide and hydrogenated for about 30 minutes with 1 g of palladium on charcoal (10%) as catalyst. The catalyst is filtered off and the dimethylformamide is removed leaving the title compound as an oil.
