Procedure
p-Nitrobenzyl (5R,6S)-3-(2-acetamidoethylthio)-6-[(S)-1-hydroxyethyl]-7-oxo-1-azabicyclo[3.2.0]hept-2-ene-2-carboxylate (e7) (100 mg) was treated with methanesulphonyl chloride and triethylamine in dichloromethane as described in Example 1. After work-up, evaporation of the dichloromethane solution afforded p-nitrobenzyl (5R,6S)-3-(2-acetamidoethylthio)-6-[(S)-1-methylsulphonyloxyethyl]-7-oxo-1-azabicyclo[3.2.0]hept-2-ene-2-carboxylate (e8) (112 mg) as a foam; νmax (CH2Cl2) 1785, 1700 sh, 1680, 1525, 1350, 1335 and 1175 cm-1.
