Procedure

A solution of 2-sulfo-2-(2-formyl-1-pyrryl)acetyl chloride (0.01 m) in ether is added to 3-[(acetyloxy)methyl]-7-amino-8-oxo-5-thia-1-azabicyclo[4.2.0]oct-2-ene-2-carboxylic acid (0.01 m) and sodium bicarbonate (0.03 m) in water. After 30 minutes the phases are separated, the pH adjusted to about 6.5 and the aqueous extracted with ethyl acetate. The ethyl acetate is separated from the aqueous phase, dried over magnesium sulfate and flash evaporated to give the title compound.
