合成路线1
该中间体在本合成路线中的序号:(VI)The reaction of 2-(3-chloropropyl)-2-(4-fluorophenyl)-1,3-dioxolane (I) with 4-aminopyridine (II) gives the corresponding pyridinium salt (III), which is reduced with NaBH4 to 2-[3-(4-aminopiperidyl)propyl]-2-(4-fluorophenyl)-1,3-dioxolane (IV). The condensation of (IV) with 2-chloronitrobenzene (V) yields 2-[3-[4-(2-nitroanilino)piperidyl]propyl]-2-(4-fluorophenyl)-1,3-dioxolane (VI), which is hydrogenated with H2 over Raney-Ni affording the corresponding amino compound (VII). Finally this compound is cyclized with carbon disulfide and KOH

合成路线2
该中间体在本合成路线中的序号:(IV)The condensation of 4-chloro-1-(4-fluorophenyl)-1-butanone ethylene ketal (I) with 4-(2-nitroanilino)piperidine (III) by means of KI in refluxing butanol gives 1-[3-(4-fluorobenzoyl)propyl]-4-(2-nitroanilino)piperidine ethylene ketal (IV), which is reduced with H2 over Raney-Ni in methanol yielding the corresponding amino compound (V). Finally this compound is cyclized with CS2 by means of KOH in refluxing ethanol
