该中间体在本合成路线中的序号：(XX)The condensation of (XVIII) with 7-beta-amino-3-(3-chloro-1(E)-propenyl)-3-cephem-4-carboxylic acid diphenylmethyl ester (XIX) affords the expected amide (XX). The halogen exchange in (XX) with I2 and NaI in acetone gives the 3-iodo-1(E)-propenyl derivative (XXI), which is treated with quinoline (XXII) in dichloromethane to provide the quinolinium salt (XXIII). Finally, this compound is fully deprotected by a treatment with TFA and anisole.
