| titleOfInvention | Process for the preparation of 7- (1H-tatrazol-1-yl) acetamidocalosporanic acid |
| abstract | The present invention relates to a process for preparing 7-n- [1H-Tetrazol-1-yl] -acetamidocfaloaperanenacids of formula I and their saltsnβ organic bases and alkali metals.nN = NnN = CHnn-ch 2 -CO-NHnEnJ-CH2OCOCH3nČOOHnThe compound of formula I, in its formnsalts are used as an intermediate in productionnpolesynthotic antibiotics Cefazoline.nwhich has a broad spectrum of actionnagainst Oram-nogative and Oram-pazitivenbacteria.nA compound of formula I of the inventionnprepares 7-aminocephalospherate by acylation of saltsnof new acid with mixed acid anhydriden1H-tetrazal-1-yl-acetic acid and suitable tertiarynacid: [ce ^ -ΖΟΗ ^ / ^ Ι ^ Ο-ΟΟΟΗ, venwherein n is 0-16, in an organic solventnand an organic salt of the compoundnof formula I is isolated by addition of an organic onena solvent in which this is minimalnsoluble. |
