合成路线1
该中间体在本合成路线中的序号:(X)2-[1(S)-(3,4-dihydroxyphenyl)-1-(diphenylmethoxycarbonyl)methoxyimino]-2-[2-(triphenylmethylamino)thiazol-4-yl]-acetic acid (IX) is condensed with 7beta-amino-3-[2-(diphenylmethoxycarbonyl)-5-methyl-s-triazolo[1,5-a]pyrimidin-7-ylthiomethyl]-3-cephem-4-carboxylic acid diphenylmethyl ester (X) by means of dicyclohexylcarbodiimide (DCC) in dichloromethane giving the protected final product (XI). Finally, this compound is deprotected by treatment first with trifluoroacetic acid and then with NaHCO3 in water.
