Abstract

A procedure to obtain cephalosporin derivatives of the formulas **(See formula)** where R1 represents hydrogen or an alcoholic group, X represents oxygen or sulfur or a group of the formula -NR2 (where R is hydrogen or an alcoholic group and, in the case of being an alcoholic group, can form a ring with R1), and R3 represents a nitrogen containing heterocyclic group, or a pharmaceutically acceptable salt thereof, comprising the production of compound (I) by reacting a compound of the formula: **(See formula)** in which each of the symbols has the same meaning as described above, or a salt thereof, with a compound of the formula: R3SH wherein R3 has the same meaning as described above, or a salt thereof.
