合成路线1
该中间体在本合成路线中的序号:(II)A new synthesis of tomoxetine has been described: The reduction of omega-chloropropiophenone (I) with NaBH4 in ethanol gives 3-chloro-1-phenyl-1-propanol (II), which is treated with butyric anhydride and pyridine in dichloromethane to yield the corresponding racemic ester (III). The optical resolution of (III) with immobilized lipase B from Candida antarctica (CALB) affords a mixture of unreacted (S)-ester and (R)-alcohol (IV) that are separated by column chromatography. Condensation of th (R)-alcohol (IV) with 2-methylphenol (V) by means of PPh3 and diethyl azodicarboxylate (DEAD) in THF gives the corresponding ether (VI), which is finally treated with methylamine in refluxing ethanol.

合成路线3
该中间体在本合成路线中的序号:(II)Reduction of 3-chloropropiophenone (I) with NaBH4 produced 3-chloro-1-phenyl-1-propanol (II). Subsequent Mitsunobu coupling of (II) with 2-(methylthio)phenol (III) in the presence of DEAD and PPh3 afforded ether (IV). Finally, substitution of the halogen of (IV) for methylamine provided the corresponding secondary amine.
