Versuchsvorschrift

(3S-trans)-2-Oxo-3-[[(phenylmethoxy)carbonyl]amino]-4-methyl-1-azetidinesulfonic acid, tetrabutylammonium salt (500 mg, 0.9 mmol) was dissolved in a mixture of water and acetonitrile. The solution was passed through an AGMP-50 ion-exchange resin column (H⊕ form, 7 ml, 1.7 meq/ml) eluting with water. The eluate was run into a flask containing 8-hydroxyquinoline (131 mg, 0.9 mmol). Acetonitrile was removed from the resulting solution under reduced pressure at <35° C. and the remaining aqueous solution was lyophilized yielding a solid. Trituration with ether and drying in vacuo afforded the desired product as a yellow powder (398 mg), melting point 61°-68° C.
