合成路线1
该中间体在本合成路线中的序号：(XIII)The benzoylation of 2'-deoxy-5-(trifluoromethyl)uridine (VI) with benzoyl chloride by means of triethylamine in dimethylacetamide gives 3-benzoyl-2'-deoxy-5-(trifluoromethyl)uridine (VII), which is benzylated with benzyl bromide and silver oxide in refluxing 2-butanone to afford 3-benzoyl-3'-O-benzyl-2'-deoxy-5-(trifluoromethyl)uridine (VIII). Finally, this compound is debenzoylated with 30% aqueous ammonia at room temperature. The deprotection of 2'-deoxy-3'-O-(thiobenzoyl)-5-(trifluoromethyl)-5'-O-trityluridine (XIII) with 0.1N HCl gives 2'-deoxy-3'-O-(thiobenzoyl)-5-(trifluoromethyl)uridine (XIV), which is submitted to desulfurization with Raney-Ni in THF.
