Versuchsvorschrift
A mixture of benzhydryl 7-tert-butoxycarbonylamino-3-(2-tosyloxyvinyl)-3-cephem-4-carboxylate-1-oxide (trans isomer) (7 g) and 3-mercaptopyridine (1.33 g) in dimethylformamide (50 ml) containing diisopropylethylamine (4.5 g) was stirred at ambient temperature for 2 hours. The resulting solution was poured into a mixture of ice-cooled water (200 ml) and ethylacetate (200 ml). The separated organic layer was washed in turn with water, 10% aqueous hydrochloric acid and a saturated aqueous solution of sodium bicarbonate and brine. The solvent was evaporated in vacuo to give benzhydryl 7-tert-butoxycarbonylamino-3-[2-(3-pyridyl)thiovinyl]-3-cephem-4-carboxylate-1-oxide. (trans isomer) (5.2 g).
