Procedure

To an ice-cooled solution of the product obtained in Step 3 (0.63 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 (0.5 g) in dry dichloromethane (20 ml) was added dicyclohexylcarbodiimide (0.178 g), and the mixture was stirred overnight 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 0.15 g of the objective compound.
