Procedure

To an ice-cooled solution containing the product obtained in Step 1 (3.0 g) and (6R,7R)-7-amino-3-[(2-diphenylmethyloxycarbonyl-5-methyl-s-triazolo[1,5-a]pyrimidin-7-yl)thiomethyl]-8-oxo-5-thia-1-azabicyclo[4.2.0]oct-2-ene-2-carboxylic acid diphenylmethyl ester (3.75 g) in dichloromethane (100 ml) was added dicyclohexylcarbodiimide (1.54 g), and the mixture was stirred at room temperature. After filtering off the insoluble matters, the filtrate was concentrated under reduced pressure, and the residue was purified by silica gel column chromatography, giving 4.8 g of the objective compound.
