Abstract

(A) Salts (I) of cephalosporin derivs. (II) with benzylamine or collidine (IV) Ar = an aromatic or heteroaromatic residue, opt. substd. e.g. by one or more hal, OH, lower alkyl, NO2, NH2 subst. NH2, lower alkanoyl, lower Oalkyl or lower Salkyl. R' = H, OAc, OH, or a substd. nucleophilic residue e.g. N3 or Oether. R2 = an N-protecting group R3 = H or an N-protecting grp. forming a ring together with R2 (B) Improved method for the purification of cephalosporins. 7beta-(D(-)-alpha-amino-alpha-phenyl-acetamido)-3-methylceph-3-em- -4-carboxylic acid (12.26 g.).
