Versuchsvorschrift

A mixture of 0.45 g (0.0014 mole) of 9-(5-amino-4-chloro-2-fluorophenyl)imino-8-thia-1,6-diazabicyclo[4.3.0]nonane-7-thione, 0.18 g (0.0014 mole) of ethanesulfonyl chloride, and 0.22 g (0.027 mole) of pyridine in approximately 30 mL of methylene chloride was stirred at room temperature for two days. The reaction mixture was heated at 26° C. for approximately 24 hours, then at reflux for 36 hours. The solvent was evaporated from the mixture leaving an oily residue. The residue was washed with an aqueous, 10% hydrochloric acid solution. The washed residue crystallized upon standing and was recrystallized from ethyl acetate and n-heptane to give 0.12 g of 9-(4-chloro-5-ethylsulfonylamino-2-fluorophenyl)imino-8-thia-1,6-diazabicyclo[4.3.0]nonane-7-thione, mp 146°-148° C., Compound 11 of Table 1.
