合成路线1
该中间体在本合成路线中的序号：(XIII)2) The condensation of 1,2,3-triazol-4-thiol (X) with bromochloromethane by means of NaH gives 4-(chloromethylsulfanyl)-1,2,3-triazole (XI) with is treated with NaI in hot acetone to afford 4-(iodomethylsulfanyl)-1,2,3-triazole (XII). The reaction of (XII) with the silver mercaptide of the 7beta-[2-[2-(tert-butoxycarbonylamino)thiazol-4-yl]-2(Z)-(triphenylmethoxyimino)acetamido]-3-sulfanyl-3-cephem-4-carboxylic acid diphenylmethyl ester 1beta-oxide (XIII) in HMPT yields the condensation product (XV), which is then treated with PCl3 in DMF to eliminate the 1beta-oxide oxygen, affording the protected compound (XVI), which is deprotected with AlCl3 in anisole, as before.
