DOCUMENT TYPE: Patent CA Section: 26 (Biomolecules and Their Synthetic Analogs) Cefoxitin was prepd. from cefalotin or a trimethylsilyl deriv. thereof via methoxylation in position 7a using a pos. chlorine donor and NaOMe in MeOH at -80° to -95°, deacetylation with aq. NaOH, and carbamoylation with chlorosulfonyl isocyanate. The acid cefoxitin is then transformed into the sodium salt using Relite CNS sodium salt ion exchange resin. .
