Procedure

To a solution of benzhydryl 7-(2-phenylacetamido)-3-chloromethyl-3-cephem-4-carboxylate-1-oxide (25 g) in N,N-dimethylformamide (150 ml) were added triethylamine (6.42 ml) and 2-propene-1-thiol (8.0 ml), and the mixture was stirred at 25° C. for 3 hours. The reaction mixture was poured into a saturated aqueous solution of sodium chloride (1.5 l), followed by collecting the precipitated solid by filtration, which was washed with water and diisopropyl ether, and then dried to give benzhydryl 7-(2-phenylacetamido)-3-allylthiomethyl-3-cephem-4-carboxylate-1-oxide (24.2 g).
