Procedure

A solution of 3-[(acetyloxy)methyl]-7-[[2-carboxy-2-(1H-indol-1-yl)acetyl]amino]-8-oxo-5-thia-1-azabicyclo-[4.2.0]oct-2-ene-2-carboxylic acid, tert-butyl ester (0.05 mole) in 10 ml of trifluoroacetic acid maintained at 0° C. is stirred for 10 minutes. The trifluoroacetic acid is removed under vacuum. The residue is treated with ethyl ether to give a solid material. Filtration gives the title compound.
