A process for preparing N-[(1R)-1-(1-naphthyl)ethyl]-3-[3-(trifluoromethyl)-phenyl]propan-1-amine hydrochloride salt of formula (I) i.e. Cinacalcet hydrochloride and its intermediates of formulae (VII) and (VIII) wherein Z is chloride or another pharmaceutically acceptable anionic counterion.

Process for preparing Cinacalcet hydrochloride

The present invention relates to a process for preparing Nebivolol and, more in particular, to a fractional distillation method of a mixture of stereoisomers of formula intermediates useful in the preparation of nebivolol.

Process for preparing nebivolol

The present invention relates to a process for preparing Nebivolol and, more particularly, to an improved method of debenzylation of a compound of formula (II) useful for preparing nebivolol endowed with high purity. 

Process for preparing Nebivolol

A process for preparing N-[(1R)-1-(1-naphthyl)ethyl]-3-[3-(trifluoromethyl)-phenyl]propan-1-amine of formula hydrochloride salt of formula (I) i.e. Cinacalcet.HCl and its intermediate of formula (IX) 

Process for preparing cinacalcet

A process for preparing N-[(1R)-1-(1-naphthyl)ethyl]-3-[3-(trifluoromethyl)-phenyl]propan-1-amine of formula (I) i.e. Cinacalcet and its intermediates of formulae (V), (Va) and (Vb). 

Process for preparing Cinacalcet

The present invention relates to a process for preparing nebivolol and, more particularly, to a process for preparing d-nebivolol and its enantiomer l-nebivolol or acid addition salts thereof starting from commercially available or easily obtainable 2,2-dimethyl-1,3 dioxolane-4-carbaldehyde and a vinyl Grignard reagent.

The present invention relates to a process for reducing a compound of formula (I) wherein X is halogen, a hydroxy group, an alkylsulfoniloxy group or an arylsulfonyloxy group; to give a compound of formula (II) as a diastereoisomerically pure compound of RS/SR configuration characterized in that said reduction is carried out by the use of (+)-B-chlorodiisopinocampheylborane or (&#x2212;)-B-chlorodiisopinocampheylborane. The compounds of formula (II) are useful as intermediates for the preparation of Nebivolol. 

The present invention relates to a process for preparing Nebivolol and, more particularly, to an improved process for synthesizing enantiomerically enriched 6-fluoro chroman alcohol or epoxide derivatives of formula, wherein R and X is defined in the description; as useful intermediates in the preparation of Nebivolol. 

The present invention relates to a process for the preparation of Nebivolol and, more particularly, to an improved method of synthesizing 6-fluoro chroman epoxides of formula (I) key intermediates in preparing nebivolol.
