A method for the preparation of Cinacalcet is disclosed comprising treating (R)-1-naphthyl ethylamine with an aromatic aldehyde to form (1R)-1-(2-naphthyl)-N-(aryl methylene)ethanamine derivative of Formula (IV), which is further treated with 1-(3-halopropyl)-3-(trifluoromethyl)benzene of Formula (V) to obtain an iminium salt of Formula (VI), followed by hydrolysis to obtain Cinacalcet free base.
揭示了一种制备Cinacalcet的方法,包括处理(R)-1-萘乙胺和芳香醛以形成公式(IV)的(1R)-1-(2-萘基)-N-(芳基亚甲基)乙胺衍生物,进一步用公式(V)的1-(3-卤代丙基)-3-(三氟甲基)苯与其反应以获得公式(VI)的亚胺盐,随后水解以获得Cinacalcet的自由基。
