合成路线1
该中间体在本合成路线中的序号：(VII)A new synthesis of 13C- or 14C-labeled SKF-86466 has been described: The Friedel Craft's condensation of labeled benzene (I) with oxalyl chloride by means of AlCl3 in CS2 yields benzoic acid (II), which is chlorinated by means of cupric chloride and thallium (III) trifluoroacetate in trifluoroacetic acid to give 2-chlorobenzoic acid (III). The reduction of (III) by means of borane/THF complex in THF affords 2-chlorobenzyl alcohol (IV), which is treated with hot concentrated HCl to afford 2-chlorobenzyl chloride (V). The Grignard condensation of (V) with N-methyloxazolidine (VI) by means of Mg in ether gives N-[2-(2-chlorophenyl)ethyl]-N-methyl-2-hydroxyethylamine (VII), which is finally cyclized by treatment with PCl5 in hot trichlorobenzene followed by addition of AlCl3 and heating at 215-25 C.
