ABSTRACT:
The invention relates to the novel compound (6R,7R)-7-(D-5-benzamido-5-carboxypentanamido)-3-(1-pyridiniummethyl)-ceph -3- em-4-carboxylate and salts thereof, which may be prepared in substantially pure form. The novel compounds are useful for the preparation of (6R,7R)-7-amino-3-(1-pyridiniummethyl)ceph-3-em-4-carboxylate or salts thereof, which are themselves useful for the preparation of 7-substituted 3-pyridiniummethyl cephalosporin antibiotics such as ceftazidime and cephaloridine.
