Procedure

To 25.3 m mole of 3-[(acetyloxy)methyl]-7-[[2-[4-(azidomethyl)phenyl]-2-carboxyacetyl]amino]-8-oxo-5-thia-1-azabicyclo[4.2.0]oct-2-ene-2-carboxylic acid in 35 ml dioxane is added 6N hydrochloric acid to give a pH of 2.5. Then 24.1 m moles N,N'-dicyclohexylcarbodiimide in 35 ml dioxane is added and the mixture is stirred at room temperature for 15 to 20 minutes followed by the addition of 24.1 m moles of 5-indanol. The mixture is stirred for 4 hours. The formed N,N'-dicyclohexylurea is removed by filtration and the filtrate is extracted 3 times with methyl isobutyl ketone. The organic extract is washed with water, dried over magnesium sulfate and concentrated to dryness in vacuo to yield 3-[(acetyloxy)methyl]-7-[[2-[4-(azidomethyl)phenyl]-2-(5-indanyloxycarbonyl]acetyl]amino]-8-oxo-5-thia-1-azabicyclo[4.2.0]oct-2-ene-2-carboxylic acid.
