Definitions
- This invention relates to a process for the preparation of N-methyl-4-
- sertraline hydrochloride which is cis-(l S,4S)-N-methyl-4-(3 ,4-
- serotonin resides in the cis-1 S,4S isomer i.e. cis-(l S, 4S)-N-methyl-4-
- hydrochloride (I) commonly known as sertraline hydrochloride.
- hydrochloride (II) are known in the literature.
- the inline was hydrogenated using 10% Pd/C as catalyst to give the
- a metal hydride reagent e.g. sodium
- titanium tetrachloride is crucial, as the reagent is moisture sensitive and
- the first object of the invention is to produce sertraline hydrochloride
- Another object of the present invention is to produce cis-N-methyl-4-
- Yet another object of the present invention is to produce the said
- the present invention provides a process for preparation
- naphthalenearnine hydrochloride i.e. sertraline hydrochloride of the
- metal catalyst such as Raney Nickel
- the invention also provides for preparation of intermediate cis-N-
- hydrochloride of formula - VI which comprises the process steps (a), (b)
- Solvent for the reaction is protic polar in the nature.
- Protic polar solvent is protic polar solvent
- lower alcohol such as C 1 -C 3 alcohols may be used.
- C 1 -C 3 alcohols may be used.
- the temperature as one of the preferred
- parameters may be varied over the range of room temperature to 100°C.
- Preferred solvent is methanol.
- Preferred hydrogen pressure is 450-500 psi
- isomer is carried out by separating all cis-isomers from the said isomeric
- naphthalenone (15.0 gm) is taken, followed by addition of 250 ml.
