Procedure

To a solution of 2,2,2-trichloroethyl α-[3-benzyl-7-oxo-2,6-diaza-4-thiabicyclo[3,2,0]hept-2-en-6-yl]-α-(1-hydroxyethylidene)acetate (450 mg) is methylene chloride (7 ml) are added methanesulfonyl chloride (0.093 ml) and triethylamine (0.48 ml) at -25° C., and the mixture is kept at the same temperature for 40 minutes. To the produced solution of 2,2,2-trichloroethyl α-[3-benzyl-7-oxo-4-thia-2,6-diazabicyclo[3,2,0]hept-2-en-6-yl]-α-(1-methanesulfonyloxyethylidene)acetate is added dropwise morpholine (0.112 ml), and the mixture is stirred for 1.3 hours. The reaction mixture is washed with water, dried, and evaporated to give residue which is purified by chromatography over silica gel containing 10% water to give 2,2,2-trichloroethyl α-[3-benzyl-7-oxo-4-thia-2,6-diazabicyclo[3,2,0]hept-2-en-6-yl]-α-(1-morpholinoethylidene)acetate (205 mg).
