Abstract
4'-Nitrobenzyl 7-phenoxyacetamide-3-hydroxy-3-cephem-4-carboxylate forms crystalline solvates with acetic acid, propionic acid and methylene chloride. The corresponding 3-hydroxy-3-cephem sulfoxide forms crystalline solvates with acetic acid, propionic acid and methanol. The described solvates allow for facile isolation and purification of 4'-nitrobenzyl 7-phenoxyacetamido-3-hydroxy-3-cephem-4-carboxylate and its 1-oxide.
