A procedure for the obtaining of the sodium salt of the acid 7- (2-tienylacetamide) 3- (1-piridyl methyl) -3-cefem-4-carboxylic betaine, in 7- (2-tienylacetamido) -3- (1-piridyl methyl) ). (Machine-translation by Google Translate, not legally binding)

摘要

A process for obtaining the sodium salt of 7- (2-thienylacetamido) 3-acetyl-oxymethyl-cephane-4-carboxylic acid, consisting of the combination of two processes, one in aqueous medium and the other in anhydrous medium, with the combination of which substantially completes the total coupling of the thienyl acetyl chloride and the subsequent formation of the sodium salt.
