실험 절차

To an ice-cooled solution of (6R, 7R)-7-[2-(2-triphenylmethylamino-4-thiazolyl)-2-(Z-hydroxyimino)acetamido]-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 (1.0 g) in dry dichloromethane (24 ml) was added potassium carbonate (0.17 g) at once, followed by dropwise addition of a solution of 4,5-bis(chloroacetoxy)-2-methylbenzoyl chloride (0.43) dry dichloromethane (16 ml) over a period of ten minutes, and the mixture was stirred at 0° C. for three hours. After filtering off the insoluble matters, the filtrate was washed twice with water, once with brine, and dried over anhydrous magnesium sulfate. The dried solution was concentrated under reduced pressure, and the residue was crystallized with ether, giving 1.13 g of the objective compound as pale yellow crystals.
