, p. 1339 - 1342 (1994)
A convenient synthesis for enantiomers of norfluoxetine, fluoxetine and tomoxetine is described. All final products were derived from a common intermediate, 3-phenyl-3-hydroxypropylamine.

The invention belongs to the technical field of medicines, and particularly relates to a preparation method of atomoxetine hydrochloride serving as a medicine for treating attention deficit hyperactivity. According to the invention, commercially available (E)-N-methyl-3-phenyl-2-propylene-1-amine is adopted as a starting material, and addition, substitution and salification are carried out so as to prepare atomoxetine hydrochloride. The preparation method provided by the invention is simple in preparation process, simple and convenient to operate, relatively high in yield and suitable for industrial production, and can provide sufficient bulk drugs for research and development of medicines.

Paragraph 0041; 0044-0047, (2019/10/15)
The invention relates to the field of medicine chemistry, and provides a preparation method of atomoxetine hydrochloride. N-methyl-3-hydroxyl-benzedrine is used as an initial raw material to take an aromatic nucleophilic substitution with o-fluorotoluene; then, through (S)-racemic ethyl mandelate resolution, salt is obtained, and the atomoxetine hydrochloride is obtained. In the route, the multistep reaction uses the continuous operation; reaction post treatment extraction and chiral resolution salt forming solvents use methyl tertiary butyl ether; during the post treatment, reduced pressure concentration operation and anhydrous sodium sulfate drying steps are not used; the operation is simple; the total yield reaches 20 to 25 percent; the purity is 99.5 percent or higher; the relevant quality standard is met. The process does not have the special reaction parameter and equipment requirements; the yield is high; byproducts are few; the post treatment is simple; the reaction yield is high; the method is suitable for industrialized production.
