合成路线1
该中间体在本合成路线中的序号:(VI)The condensation of 1-naphthol (I) with an excess of o-dichlorobenzene (II) at 100 C by means of anhydrous AlCl3 gives 4-(3,4-dichlorophenyl)-1-tetralone (III), which is allowed to react with N-methylhydroxylamine (IV) and NaOAc in refluxing ethanol, yielding the nitrone (V). The reduction of (V) with H2 over RaNi in methanol affords a racemic cis/trans (9:1) mixture of methylamines, which by crystallization of its hydrochloride in ethanol provides pure (racemic)-(cis)-(VI). Finally, the target (1S)-(cis)-compound is obtained by optical resolution of (VI) with (R)-(-)-mandelic acid.

合成路线2
该中间体在本合成路线中的序号:(rac)-(cis)-(III)The reaction of 4-(3,4-dichlorophenyl)-1,2,3,4-tetrahydronaphthalen-1-one (I) with methylamine and formic acid in DMF gives the corresponding methylimine (II), which is reduced with H2 over Pd/C to yield (rac)(cis)-4-(3,4-dichlorophenyl)-N-methyl-1,2,3,4-tetrahydronaphthalen-1-amine (rac)(cis)(III). Finally, this compound is submitted to optical resolution by means of mandelic acid to afford the target (1S)(cis)-sertraline.
