    摘要: There is described a process for the manufacture of carboxylic acid amides by acylating amines with 2-benzothiazolyl thioesters of carboxylic acids, which process comprises reacting the amine in the form of an acid addition salt. This process is especially of great advantage when the amine is not particularly stable in the form of the free base, which is frequently the case especially with 7-aminocephalosporin derivatives. 7-Acylamino-cephalosporin derivatives can be manufactured in good yield and in high purity with the novel process.
