-
Page/Page column 17; 18, (2008/12/05)
The present invention relates to the process for preparing Atomoxetine hydrochloride which is a selective norepinephrine reuptake inhibitor. Atomoxetine HCl is chemically known as (-)-iV-Methyl-3-phenyl-3-(o-tolyloxy)-propylamine hydrochloride and represented by formula (I). More particularly, the invention relates to crystalline form of N-methyl-3-phenyl-3-(o- tolyloxy) propylamine oxalate (here in after referred as "(±) Atomoxetine Oxalate"), which is an useful intermediate for the synthesis of Atomoxetine hydrochloride.

Efficient method for preparing 3-aryloxy-3-arylpropylamines and their optical stereoisomers
-
Page/Page column 7; 8, (2008/06/13)
Provided is an efficient method for the preparation of 3-aryloxy-3-arylpropylamines, their optical stereoisomers, and pharmaceutically acceptable salts thereof. The process allows for the isolation of 3-aryloxy-3-arylpropylamines in high yield and purity. The present invention further relates to a process for producing fluoxetine, tomoxetine, norfluoxetine, duloxetine, nisoxetine, and their optically enriched (R)— and (S)-enantiomers.
