  • 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

  • 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.
