Abstract

NEW MATERIAL:The compound of formula I. USE:Intermediate for cephalosporin compound. PREPARATION:A compound of formula II (R<1> is protected amino; R<2> is protected carboxy; X<-> is anion) [e.g. 7-(2-hydroxybenzylidene-amino)-3-(2-methyl-1-pyrazolio) methyl-3-cephem-4-carboxylic acid benzhydryl ester iodide] is subjected to the reaction to eliminate the amino- and carboxyl-protecting groups.
