实验过程

To a solution of 2,2,2-trichloroethyl α-[3-phenoxymethyl-7-oxo-4-thia-2,6-diazabicyclo[3,2,0]hept-2-en-6-yl]-α-(1-methanesulfonyloxyethylidene)acetate (1.52 g) in benzene (30 ml) is added morpholine (0.48 ml) at beneath 10° C. After stirring for 1 hour, the mixture is washed with water, dried, and evaporated. Purification of the obtained residue by chromatography over silica gel gives 2,2,2-trichloroethyl α-[3-phenoxymethyl-7-oxo-4-thia-2,6-diazabicyclo[3,2,0]hept-2-en-6-yl]-α-(1-morpholinoethylidene)acetate (0.76 g). Yield: 50%.
