The reduction of (IV) with LiAlH4 in ether affords (-)-3-hydroxy-N-methyl-3-phenylpropylamine (V), which is protected with di-tert-butyldicarbonate to the amide (VI). The condensation of (VI) with o-cresol (VII) by means of triphenylphosphine and diethylazodicarboxylate (DEAD) in ether yields the protected final product (VIII), which is finally deprotected with dry HCl in methanol. 〖作者〗 Dike, S.Y.; Kumar, A.; Ner, D.H. 〖参考〗 Dike, S.Y.; Kumar, A.; Ner, D.H.; A new chemoenzymatic enantioselective synthesis of R-(-)-tomoxetine, (R)-fluoxetine and (S)-fluoxetine.
