摘要:There is described a process for the preparation of cinacalcet hydrochloride (I) which includes the steps of: a) reacting (R)-(+)-1-(1-naphthyl)ethylamine (II) with 3-[3-(trifluoromethyl)phenyl]propenaldehyde (III) to afford the non isolated intermediate (R)—N-[3-[3-(trifluoromethyl)phenyl]-2-propenylimino-N-[1-(1-naphthyl)ethylamine (IV); b) reducing the non isolated intermediate (R)—N-[3-[3-(trifluoromethyl)phenyl]-2-propenylimino-N-[-1-(1-naphthyl)ethylamine (IV) with a sequential addition of:—a solution of sodium borohydride, methanol and a base,—oxalic acid and—a base to obtain (R)—N-[3-[3-(tifluoromethyl)phenyl]-2-propenyl]-1-(1-naphthyl)ethylamine (V) by passing through the precipitation of the oxalate salt of compound (V) after the addition of oxalic acid; c) hydrogenating (R)—N-[3-[3-(trifluoromethyl)phenyl]-2-propenyl]-1-(1-naphthyl)ethylamine (V) thus obtaining (R)—N-(3-(3-(trifluoromethyl)phenyl]propyl]-1-(1-naphthyl)ethylamine cinacalcet base (VI), which is retaken in ethyl acetate; and d) treating the solution of cinacalcet base (VI) in ethyl acetate with hydrochloric acid to afford cinacalcet hydrochloride (I).

摘要:The present invention relates to a process for preparation of nitrosamine free Cinacalcet (1) and salts thereof. Wherein, Cinacalcet (1) and its salts is substantially free of nitrosamine impurities by using of an antioxidant in the process for synthesis of Cinacalcet (1) and its pharmaceutically acceptable salts.

标题 :Process for the preparation of cinacalcet hydrochloride
权利人:SANDOZ AG
摘要:The present invention relates to a process for the preparation of cinacalcet hydrochloride which is industrially feasible and commercially viable. The synthesis of cinacalcet hydrochloride is carried out by the condensation of 3-trifluromethylphenyl propionic acid with R-(+)-1-(lnaphthyl)ethylamine.

摘要:The present invention provides an improved process for preparation of organic compounds represented by Formula-Z; wherein effectively minimising the formation of dehalogenated by-products is achieved. In the process, the reduction is carried out using suitable reducing agent; more preferably Lithium Aluminium Hydride (LAH) in a solvent system, wherein at least one of the solvent is selected from halogenated solvents, which acts as co-solvent. The process of the present invention is useful for minimising of the formation of dehalogenated by-products during synthesis of various active pharmaceutical ingredients such as Paroxetine Hydrochloride, Cinacalcet, Eletriptan and Asenapine.

摘要:The present invention relates to novel dihydronaphthalene compounds, compositions, methods for using the same, and processes for preparing the same. The present invention also relates to novel total synthesis approaches for preparing these compounds. In addition, the present invention relates to methods of producing quantities of isomers of these compounds and separating and purifying them using chiral separation techniques. The present invention also relates to methods of producing quantities of a single isometric compound without the need for chiral separation techniques.
