    摘要: An ester of 7-acylamido-3-acylthio-3- or -2-cephem-4-carboxylic acid represented by general formula (1) ##STR1## wherein R.sup.1 is an acyl group, R.sup.2 is a carboxyl-protecting group, R.sup.3 is a lower alkyl group, an aryl group or a substituted aryl group, or a mixture of two or more of said ester is used as the starting compound and is reacted wit a tertiary amine and also a secondary amine. Then the tertiary amine salt compound as formed as the reaction product is reacted with a compound of formula (4)R.sup.4 --X (4)wherein R.sup.4 is a lower alkyl group, a cycloalkyl group or a heterocyclic group or a heterocyclic group-substituted methyl group and X is a leaving group, whereby the desired ester of 7-acylamido-3-substituted thio-3-cephem-4-carboxylic acid of formula (5) ##STR2## can be produced preferentially, conveniently and efficiently.
