Zusammenfassung:	7-Amino-3-(3-formamidopyridinium)methyl-3-cephem-4-carboxylate of the formula is produced by (a) reacting a compound of the formula in which R3 is phenacetyl or a thienylacetyl group, with 3-formamidopyridine to give the compound of the formula and (b) spliting off the R3 radical. The product can then be coupled to a suitable acid to produce a cephalosporin and the formyl radical may be split off.
