Abstract
The invention relates to a method for obtaining cefotetan acid substantially free of tautomer, by treating crude cefotetan with Alions which cause the tautomer to precipitate. The precipitate is eliminated by filtration to provide a solution from which practically tautomer-free cefotetan is obtained.
