Abstract

Solutions of 7-amino cephalosporanic acid are obtd. at considerably lower cost by use of acrylic amidines of formula (I), in which R1 and R1' are aliphatic or aromatic gps. and R2 and R2' are aliphatic or aromatic gps., or together form a cyclic gp. - They are reacted with an organic solvent suspension of a 7-amino cephalosporanic acid, and the soln. obtd. is added to an acylating agent to provide a corresp. cephalosporin.
