PROCEDURE

实验过程

A mixture of 450 mg of (6R-trans)-3-[(acetyloxy)methyl]-7-[(aminothioxomethyl)amino]-8-oxo-5-thia-1-azabicyclo[4.2.0]oct-2-ene-2-carboxylic acid, diphenylmethyl ester, 195 mg of 3-bromo-2-oxopropanoic acid, ethyl ester, 70 mg of potassium carbonate and 7 ml of acetonitrile was stirred overnight and then filtered through hydrous magnesium silicate. The filtrate was evaporated, giving 510 mg of (6R-trans)-3-[acetyloxy)methyl]-7-[[4-(ethoxycarbonyl)-2-thiazolyl]amino]-8-oxo-5-thia-1-azabicyclo[4.2.0]oct-2-ene-2-carboxylic acid, diphenylmethyl ester.
