    • Racemic N -benzyl- N -methyl-3-(2-methylphenoxy)-3-phenylproρylamine (VIII) is an intermediate for obtaining atomoxetine. Racemic N -benzyl- N -methyl-3-(2-methylphenoxy)-3- phenylpropylamine (VIII) further reacts in a solution of an organic solvent with an optically active acid producing a mixture of diastereoisomers, which are subsequently resolved by crystallization and converted to the respective (R) and (S) enantiomers of N-benzyl-N-methyl- 3-(2-methylphenoxy)-3-phenylpropylamine by treatment with an organic or inorganic base. The (R)-enantiomer of N-methyl-3-(2-methylphenoxy)-3-phenylpropylamine ((R)-VIII) is further subjected to debenzylation by means of an alkyl or aryl chloro formate yielding an alkyl/aryl (R)-3-(2-methylphenoxy)-3-phenylpropylmethylcarbamate ((R)-IX), which is then hydrolyzed in the basic environment yielding the base of (R)-N-methyl-3-(2-methylphenoxy)- 3-phenylpropaneamine, which is finally converted to (R)-N-methyl-3-(2-methylphenoxy)-3- phenylpropanamine hydrochloride ((R)-I) by treatment with hydrochloric acid.
