The present invention provides isolated N-methyl-3-(3-methylphenoxy)-3-phenylpropylamine hydrochloride, and preparation thereof as well as of N-methyl-3-(4-methylphenoxy)-3-phenylpropylamine hydrochloride and of N-methyl-3-phenoxy-3-phenylpropylamine hydrochloride. The invention further provides the use of the above compounds as reference markers and/or reference standards during the synthesis of Atomoxetine. Also provided is a method of limiting the amounts of the impurities 3FT (3-fluorotoluene), 4FT (4-fluorotoluene), and FB (fluorobenzene) in the 2-fluorotoluene starting material used in the synthesis of Atomoxetine Hydrochloride. The purity of the Atomoxetine Hydrochloride product is ensured by determining the amounts of 3FT, 4FT, and FB in the 2-fluorotoluene starting material with the marker 3-ATM HCl.
本发明提供了N-甲基-3-(3-甲基苯氧基)-3-苯基
丙胺盐酸盐的分离物,以及其制备方法,以及N-甲基-3-(4-甲基苯氧基)-3-苯基
丙胺盐酸盐和N-甲基-3-苯氧基-3-苯基
丙胺盐酸盐的制备方法。本发明进一步提供了上述化合物在合成阿
托莫西汀期间作为参考标记物和/或参考标准物的用途。还提供了一种限制合成阿
托莫西汀盐酸盐时
2-氟甲苯起始材料中杂质3FT(
3-氟甲苯)、4FT(4-
氟甲苯)和FB(
氟苯)量的方法。通过使用标记物3-ATM HCl确定
2-氟甲苯起始材料中3FT、4FT和FB的含量,确保阿
托莫西汀盐酸盐产品的纯度。
