Claims

exact text as granted — not AI-modified
1 - 39 . (canceled)  
     
     
         40 . A process for the preparation of sertraline hydrochloride polymorphic form II, wherein a solution of sertraline free amine is seeded with some crystals of polymorphic form II and hydrogen chloride is added.  
     
     
         41 . The process of  claim 40 , wherein hydrogen chloride is added as a gas.  
     
     
         42 . A process of  claim 40 , wherein the solution of sertraline free amine is seeded with some crystals of polymorphic form II and subsequently hydrogen chloride is added.  
     
     
         43 . The process of  claim 42 , wherein hydrogen chloride is added as a gas.  
     
     
         44 . A process of  claim 40 , wherein hydrogen chloride is added to the solution of sertraline free amine and subsequently the solution is seeded with some crystals of polymorphic form II.  
     
     
         45 . The process of  claim 44 , wherein hydrogen chloride is added as a gas.
