    • 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.
    • 外消旋N-苄基-N-甲基-3-(2-甲基苯氧基)-3-苯基丙基胺(VIII)是获得阿托西汀的中间体。 外消旋N-苄基-N-甲基-3-(2-甲基苯氧基)-3-苯基丙胺(VIII)进一步在有机溶剂与光学活性酸的溶液中反应,产生非对映异构体的混合物,其随后通过结晶和 通过用有机或无机碱处理转化成N-苄基-N-甲基-3-(2-甲基苯氧基)-3-苯基丙胺的各自的(R)和(S)对映异构体。 N-甲基-3-(2-甲基苯氧基)-3-苯基丙基胺((R)-VIII)的(R) - 对映异构体进一步通过烷基或芳基氯甲酸酯进行脱苄基,得到烷基/芳基(R )-3-(2-甲基苯氧基)-3-苯基丙基甲基氨基甲酸酯((R)-IX),然后在碱性环境中水解,得到(R)-N-甲基-3-(2-甲基苯氧基) - 苯基丙胺,最后通过用盐酸处理转化为(R)-N-甲基-3-(2-甲基苯氧基)-3-苯基丙胺盐酸盐((R)-I)。
