摘要:
Disclosed herein are convenient, industrially advantageous and environmentally friendly processes for the preparation of cinacalcet hydrochloride. Disclosed also herein are novel hydrochloride, oxalate and di-p-toluoyl-L-(+)-tartrate salts of (R)-α-methyl-N-[3-[3-(trifluoromethyl)phenyl]propylene]-1-naphthalenemethaneamine (unsaturated cinacalcet), solid state forms of the salts, and a process for their preparation thereof.
摘要:
Provided herein are impurities of cinacalcet, (R)-α-methyl-N-[3-[3-(trifluoromethyl)phenyl]propyl]-1-(5,6,7,8-tetrahydronaphthalene)methaneamine (tetrahydro cinacalcet impurity), (R)-α-Methyl-N-[3-[3-(trifluoromethyl)phenyl]propyl]-1-naphthalenemethaneamine-N-oxide (cinacalcet N-oxide impurity) and (R)-α-methyl-N-[3-[3-(trifluoromethyl)phenyl]methyl]-1-naphthalenemethaneamine (benzylamine impurity); and processes for preparation and isolation thereof. Provided further herein is a highly pure cinacalcet or a pharmaceutically acceptable salt thereof substantially free of impurities, processes for the preparation thereof, and pharmaceutical compositions comprising highly pure cinacalcet or a pharmaceutically acceptable salt thereof substantially free of impurities.
